Re: Problems with [EMAIL PROTECTED] in Performa 475
From: [EMAIL PROTECTED] Date: Wed, 1 Feb 2006 21:54:06 +0100 Hello! I wan't to change the [EMAIL PROTECTED] to a [EMAIL PROTECTED] in my Performa 475. The two Chip's are pin compatible and the P475 starts booting, but short after Welcome-Message it stop's with BUS-Error. I cannot boot from a known good external Zip, the P475 ignores the drive. I did no overclocking. The 68040 should run with 25 MHz. Does the 68040-40MHz double the Bus-speed or external timer signal? Must I use a 68040-25 or 33 MHz Version? No, they should all be plug-in compatible. I've replaced 68040/40s with all manner of slower/older 68040 and 68LC040s and vice versa. You may have bent one of more pins when you inserted it in the socket. Have you tested the 40MHz chip in any other machine to make sure that it works properly? BTW: Vintage Mac's merged with Compacts? Should I post to Vintage Mac's from now on? Quadlist, Vintage Macs and Compact Macs are now all one single list. The traffic on at least two of those was getting pretty thin. Jeff Walther -- Compact Macs is sponsored by http://lowendmac.com/.

Re: New Low End Mac email lists
Date: Wed, 25 Jan 2006 23:33:30 -0800 From: NODEraser [EMAIL PROTECTED] Whatever happened to ye-olde UseNet newsgroups? About the only use I've heard for them lately, is pictures and video. And the subscription fees for that are pretty nasty. I remember that many ISPs offered free newsgroup access, but that was back in the days when text was the primary use for said medium. The comp.sys.mac.*** hierarchy is still around and reasonably active. However, the proliferation of web based fora have significantly dented the number and frequency of participants. It's sad because it causes a dilution of the community and while you could pretty much count on meeting everyone active in Macdom on the news groups, now days, if you don't hit every website, you're going to miss some great people somewhere. I was quite active reading those newsgroups and now rarely visit. I remember seeing Clark Martin's (a regular poster to this list) postings on Usenet regularly as well but can't say if he's still participating or not. Comp.sys.mac.wanted, which was the best, free place to exchange, sell and buy Mac related stuff is pretty much dead now. Ebay killed it. Or rather the sellers and buyers have all moved to Ebay. It's too bad, because now you can pay huge fees to sell things (and indirectly to buy things) that once folks bought and sold for free. Plus, if an item was clearly bogus and listed in comp.sys.mac.wanted, someone was sure to drop by and post a message pointing out the blunder. Ebay claims that they offer security and protection, but I've had more per-exchange problems on Ebay than I ever had in the news groups. In news groups, if someone was a scammer, his name got posted around enough to alert anyone willing to do a little searching, pretty quickly.

Plus and Pre-Plus Keyswitches and Caps?
I've been kind of collecting bits that will let me keep my old Macs going as long as I keep going. One thing that has concerned me lately are the keyswitches and to a lesser extent the keycaps on the old Plus and pre-Plus keyboards. I imagine that there are some folks here who are Apple II afficianados as well as Mac fans. Are the keyswitches in the IIe keyboards the same as in the Plus keyboard? No-one else was bidding on it, so I picked up a lot of 10 new IIe keyboards on Ebay, mainly for the keyswitches and possibly the keycaps. Now, do I have useful Plus parts, or just a lot of components for a computer that was discontinued before I could afford a computer?

Re: Boot Partition Selection
Date: Mon, 19 Dec 2005 15:47:11 -0700 From: Thomas [EMAIL PROTECTED] I installed a larger hard drive in my SE/30 and made a few partitions to be able to boot different OS versions, but I'm having difficulting specifying which volume to boot from. I used the startup disk control panel to select the partition I wanted to boot, and then when I open the control panel again to confirm it made the selection, it shows all the partitions as being selected. When I reboot, the first partition always boots no matter which partition I choose. The system folders in the other partitions are blessed. For the older operating systems (pre 7.6?) one needed a utility usually included with the disk formatting software, in order to set which partition to boot from. APS PowerTools and FWB Hard Disk Tool Kit included utilities or features that allowed one to choose a boot partition among other functions. It might be an interesting experiment to try the Start-Up Disk CP from 7.6.1 with the earlier OSs. Jeff Walther -- Compact Macs is sponsored by http://lowendmac.com/.

Would it be possible to use the NUBUS adapter from the IIsi, stick in in the SE/30 for a NUBUS SE/30? Until someone tries it, I don't think we're going to know the answer to that one. However, I suspect that there would be major mechanical issues as far as fit goes. I had such a project in mind but on the very rearmost burner. Actually, was planning to trace the connections on the card, build a new circuit board that would fit, and transfer the chips from the IIsi adapter to my card. However, Goodwill got rid of the bin full of IIsi adapters here. So much for my cheap source of experimental parts. I could have bought them when I thought of the idea, but I am never going to get to many of the projects I envision and have realized I must not buy parts until I'm really ready to begin a project.

Re: SE/30 PDS question
Subject: Re: SE/30 PDS question Date: Thu, 24 Nov 2005 09:48:21 - From: Brierley, Paul [EMAIL PROTECTED] This seems such a simple idea, I can't believe it never occurred to me before! However, the Asante card does have a series of jumpers for setting the card id so that it doesn't conflict with whatever is in the passthrough slot. It seems quite feasible that these jumpers would simply affect the card's timing with respect to the system bus. If that is indeed the case, then we could just be looking at two cards connected in parallel. Hmmm... Maybe I should dig out a voltmeter and do some studying... I'm pretty sure that the jumpers set which chunk of address space the card uses. In other words, the driver for the card provides the software support so that the CPU can send data to certain addresses which are not in RAM or any of the built-in IO. The PDS card watches for those addresses on the address bus (through the PDS slot) and when a transaction comes along destined for a certain set of addresses, the PDS card handles that transaction. The available address space is allocated to slots which would be the NuBus slots in a machine with NuBus. So you can change which slot the PDS card is pretending to be in. All it really changes is which set of address the PDS card uses. But since you don't want two PDS cards trying to use the same set of addresses, it's good to be able to change one card's address.

It was like chasing a phantom... Watch ebay. I think most commonly they came with a 90 degree bend for the Mac II's. I guess you're referring there to the Daystar SE/30 and IIsi adapters for the Powercache 030 (and I think the Turbo 040).The Daystar cards won't work natively in an SE/30, and need one of these adapters. I'm thinking of something simpler, just a passive two-way splitter for cards native to the SE/30, like the Xceed Color 30 and Asante MacCon ethernet cards. I don't see why it wouldn't work, but I want to be careful! Around here somewhere I have an example of what you are looking for. It's the only one I've ever seen. It is a simple splitter for the PDS slot--no circuitry on board. It may actually be for the IIsi rather than the SE/30 as both sockets are at a right angle, which would make a lot more sense for the horizontally oriented IIsi. The manufacturer was SuperMac (the video card company, not the Umax Mac clone company) and it has a heavy metal back on the card. The Daystar adapters typically have one PDS pass-through slot and one cache slot that has a bit of circuitry in a PLD to make the cache slot look like a IIci slot which is what Daystar's upgrades require.

Tedious, but not really challenging. Oh. But does the Classic use a DIP or a PLCC? If a PLCC, it's a little more difficult to snip the pins on the old CPU, but a little easier to desolder the pins and clean the pads afterwards.

I do indeed have Snooper (albeit 75 miles away for the next few weeks) so I might run it on that Mac when I get back. I don't get bombs, but it seems to hang more often than my other Macs...and I'm not doing anything that intensive on it plus it has 4MB RAM. I love this particular Plus so I am curious now as to the status of the 68K chip in there. I haven't followed this thread as well as I should, but have the folks with the problems checked their power supply output to confirm that their logic boards are getting good 5V? With age these old power supplies sometimes slip down to lower voltages, and at some point, too low voltage creates weird symptoms in semiconductors.

Re: SE/30 Woes!
Date: Tue, 25 Oct 2005 13:12:47 +0100 From: Liam Proven [EMAIL PROTECTED] It's also a *lot* easier than trying to remove and replace the failed cap, especially if you are not familiar with component-level electronics work, particularly soldering. Added to this, more modern computers from the 1990s often used robots to do the soldering, allowing tricky techniques for humans such as surface-mount attachment instead of the older pin-through-hole attachment. These are really difficult for even a skilled solderer to replace, and when you consider that the parts may be hard to obstain and the contacts on the board corroded, it's an uphill battle. Personally, I find the surface mount components *a lot* easier to replace than the through hole stuff. I often have trouble with through-hole leads sticking to the plated through part of the hole. This is especially problematical when desoldering a DIP chip, where all the leads need to release simultaneously. YMMV Jeff Walther -- Compact Macs is sponsored by http://lowendmac.com/.

Early Mac Memory; Was: Re: music
Date: Mon, 24 Oct 2005 03:18:29 +0200 From: =?ISO-8859-1?Q?Antonio_Rodr=EDguez?= [EMAIL PROTECTED] Well, for what I read in Folklore.org (a great site about the history of the Mac's development, written and maintained by Andy Hertzfeld, Macintosh system software lead engineer), the 128's motherboard actually allowed you to raise the RAM to 512 Kb by replacing the 64 kbit chips with 256 kbit ones. I think, also, that the ROM was prepared from the beginning to detect how much RAM was present and use it all (up to the 8 Mb limit imposed by the 24-bit addressing mode, that is). I also think the kind of RAM chips used was the only change between the 128k and the unenhanced 512k. Unfortunately, the memory map for the 128K, 512K and Plus all have the ROM mapped at $40 000, which is 4 megabytes. Additionally, the Mac Plus (and therefore 512KE) have the SCSI mapped at $58 to $60 (5.5 MB - 6 MB). I think it would be rather challenging to put the RAM from $00 to $40 and then have it take up again at $42 . On the other hand, I wonder how much of a hacking job it would be to remap the ROM to $80 - $82 and the SCSI to $88 to $90 . The address space from $80 to $90 appears unused. One would need to change some GLUE chips as well as the ROM code, I suppose, which is probably doable. I mean, they got Mini vMac working, right. But I suspect that one would also have to patch ToolBox mapping tables in the various OSs. It would be cool to hack 8 MB of RAM into these old machines, but the memory map coded into the hardware and ROM make it not very feasible.

Re: SE/30 Woes!/What is 'Simasimac'?
Capacitors can be purchased from any of several on-line electronic component suppliers. I typically use Digi-Key http://www.digikey.com, Mouser http://www.mouser.com or JDR http://www.jdr.com. Digi-Key probably has the largest selection, and in my opinion their website has the best user interface on their search engine. However, they have a $25 minimum. If you don't meet the minimum they charge a $5 surcharge. Digi-Key will ship by USPS Priority Mail and for most assortments of electronic components, that means $3.85 for shipping. That's a nice change from $7 - $10 that other places charge. Digi-Key will ship internationally for a $6 surcharge. Mouser is probably a better choice if they have it in stock. Their prices on components seem to be lower (have been on the items I've sampled) and I don't think that they have a minimum. Their shipping will run a bit more. I haven't actually used JDR in a while, but felt compelled to include three choices. Desoldering the surface mount capacitors is actually one of the easiest soldering jobs there is. The trick is to use two soldering pencils simultaneously. Heat both sides of the capacitor and it will gently lift off. Radio Shack has grounded 15W soldering pencils for under $10 each. To solder a new cap in place, first clean the pads of left over solder with a soldering pencil and desoldering braid. I prefer the Chemtronics braid to the stuff they sell at RS (Easy Braid?). It seems to work better, but maybe I'm weird. Digi-Key has the Chemtronics braid. At this point in the procedure is a good time to clean your circuit board using a mild solvent. 95% isopropyl alcohol or even 70% (rubbing alcohol) will work pretty well. Just don't leave little cotton fibers behind, if you use cotton balls. You can also buy Flux-Off at Fry's and some other stores. This is a fairly noxious aerosol flux remover that works great for cleaning circuit boards. This is also a good time to carefully inspect you board and determine if the corrosive leaked by the caps ate anything important. To solder a SM cap in place, tin one pad. Then use one hand to place the cap on the board and use the other hand to wield the soldering pencil and melt the solder on the tinned pad. Once the cap is positioned, remove the pencil and hold the cap in place for a few seconds while the solder hardens. Now solder the other side. You'll probably want to use tweezers or some such to maneuver the small SM caps. Jeff Walther -- Compact Macs is sponsored by http://lowendmac.com/.

Antwort: Re: Startup-Stripes on Classic II
From: [EMAIL PROTECTED] Date: Thu, 13 Oct 2005 21:18:03 +0200 Replacing the capacitors on a Classic II will be hard work: All of them are SMD-Parts (Surface Mounted Device). You will need a very very very fine soldering iron when you try to replace them. On productionline SMD's are first glued to their position and then soldered. In 1990 the soldering was done by pulling the board thru a liquid wave of hot soldering tin. The soldering tin is flowing to all parts on the front side, only a minimum of solder will stick to the metal. Some varnish on the board prevents solder vom sticking to the rest of the board. All plastic parts (RAM sockets, ...) were mounted later and were soldered from the back side. The SMD's won't be harmed because the cold board is just a second above the soldering wave. Replacing SMD's with a soldering iron will be difficult because of the glue and the small size of the soldering points. Replacing surface mount caps need not be difficult. Use two soldering pencils. Apply one pencil to each contact of the SMD capacitor simultaneously. This melts the solder on both sides and if you wait a bit, the glue will melt too. Then the capacitor lifts off easily. The points need not be particularly fine. If you live in a place where there are Radio Shack stores, a pair of the $10 grounded soldering pencils works well. This page http://homepage.mac.com/schrier/mhz.html has instructions for this method, although they use it for moving SMD resistors. Jeff Walther -- Compact Macs is sponsored by http://lowendmac.com/.

Re: Printer for my compact macs
Date: Fri, 23 Sep 2005 21:26:24 +0100 From: Mike [EMAIL PROTECTED] I am thinking about picking up a cheap (and small) laser printer for use with my networked macs, it would also be great if my XP and Linux boxes could print to it as well . Does anyone know of any suitable *cheap* laser printers that I could use with compacts ranging from system 6 (Pluses) to 7.5.5 (SE/30s Mystic) ? I was looking at a cheap LaserWriter 4/600 (nice and small, I don't want a monster sized one !) but specs on the net seem to imply it is local talk only. Any recommendations would be gratefully received. If you can find one locally, the HP LaserJet 4M Plus was a great printer. I say locally, because the shipping will kill you otherwise. These printers sell for about $50 - $70 around here. They have a slot for an HP MIO card, which comes in various flavors. One flavor has LocalTalk and ethernet on the same card, which is very convenient. Often, one can find the HP printer with the desired MIO card already installed, since many sellers don't seem to know or care about the MIO cards installed. I've heard that the HP 5M is similar and similarly robust, but have no personal experience with those. If true, it might be a better choice as the 4 is reaching the age where replacement parts may become scarce. Supplies should not be a problem for a long time because the print engine is very common. The HP LJ 4M Plus has a 500 sheet paper tray option and a duplexer option and the cool thing about these two options is that the sit under the printer and just make it taller. They don't increase its footprint. The HP LJ4 Plus (no 'M') is identical except that it lacks the Postscript module which you need for Mac printing. But sometimes you'll find an LJ which just says 4 on the label but actually has the Postscript module installed. Printing out the printer info page will detail which options and how much memory are installed. Jeff Walther -- Compact Macs is sponsored by http://lowendmac.com/.

I wonder whether this ROM version is rare enough for someone to give the board a home. Perhaps someone can, but I can't. The relevant numbers would be the 342-0341-A and 342-0342-A numbers. Besides, I always thought the Mac 128K and 512K had two 32Kbyte ROM chips (Laurel and Hardy), and the Mac Plus had one 128K chip (Mr. T). What is this Mac Plus logic board doing with two ROM chips? Nope, two ROM chips each. The ROM chips are 8 data bits wide, and the Mac Plus has a 16 bit wide data bus, so it takes two 8 bit chips to fill the 16 bit bus. And from Apple's Tech Note HW_11 Macintosh Plus ROM Versions Macintosh Plus ROM history Readers Digest® condensed version of Macintosh Plus ROM history, or the truth according to Bo3bdar the everpresent: 1st version (Lonely Hearts, checksum 4D 1E EE E1 ): Bug in the SCSI driver; won't boot if external drive is turned off.

Re: .047 Thick Copper Clad Board for PCBs
From: Chris \Zap\ [EMAIL PROTECTED] Subject: Re: .047 Thick Copper Clad Board for PCBs Date: Fri, 26 Aug 2005 20:46:15 -0400 As an addition, I have looked into PCB prototyping and the 4pcb.com deal, as well as others, and they seem to actually be quite a good deal for what they offer. I wouldn't think it would take much work to lay the board out with their software if they want a specific format, but they may limit you to one usable item per board, aka... not putting 10 SIMMs on one board. So, you end up with 3 prototypes, and you can order more with greater variable specifications, and without any tooling costs. I can't see how trying to do it all yourself would be better than using even a lower end boardhouse. Obviously, a normal boardhouse will give you a real, 100% item, but is that necessary for what is being made? It should still work either way, and if the lesser cost means that it actually happens, then why not? The problem with the prototype services is that they are very restrictive in their specifications, and one of those restrictions is that the board will be .062 thick. So, if you were making a ROM DIMM for the x100 PowerMacs, x500s or Beige G3, e.g., the proto services would be fine, because those boards are .062 thick. But for SIMMs in our old Compacts and in the vintage machines, you need .047 and the affordable proto services won't do .047. You must pay for the full-service PCB builds to get non-.062 board.

.047 Thick Copper Clad Board for PCBs
About 2 years ago Gamba and I collaborated on making a ROM SIMM to fit the SE/30, which had the IIci ROM code on board. When we were nearly done we discovered that the ROM SIMM in the SE/30 is around .050 thick, whereas all the modern PCBs and commonly available laminate stock is .062 thick. As it happens, the circuit boards for 30 pin SIMMs are also .050 thick. Anyway, I found that this seller on Ebay, http://search.ebay.com/_W0QQsassZstarstreasuresQQhtZ-1 has several lots of .047 thick copper clad laminate stock.No connection, relationship, etc. I don't know if anyone else is making boards, but if you are, this could be useful. I've been thinking about trying to make some IIfx SIMMs... On the topic of PCB making, if one starts with copper clad stock, how does one put a photosensitive surface on it, so that one can do photolithographic circuit board masking for etching? Is there some kind of stick-on material? The only clue I came up with seemed to indicate that one needed an expensive laminating machine. Jeff Walther P.S. Gamba, I hope you're still out there.

Re: Mac Portable
Date: Thu, 18 Aug 2005 20:50:28 -0500 From: Richard Ballard [EMAIL PROTECTED] Subject: Mac Portable Just got my new Mac Portable in. It's pretty compact. May we talk about it here or will that result in my shoestrings being tied together and my garage door duct taped shut? I have been having a bit of curiosity about the Mac Portable recently. I don't have one, nor do I especially want one, but I do have Outbound Laptop Model 125s. The similarities in some parts of the design are curiously similar, such that I've developed a desire to see the logic board of a Mac Portable. E.g. there's an unused HD15 port which was going to be a sort of digital video out port on both of them, so I'm told/have read. If someone has his or hers dissected at some point and would be kind enough to do a scan of the front and back, I'd appreciate it. Better yet, I would love to get my hands on a dead logic board some time (don't need a live one to satisfy my curiosity). A minor irony is that about ten years ago I bought a large lot of Apple Service Parts at auction and two Mac Portable logic boards were included but I sold them to a company that specialized in Mac Portable support and repair almost immediately. Back then I had no particular interest in them. How is your hard drive? I had one of those in that lot of parts too. It had a funky cable on it, but it looked as if it would not be so difficult to build an adapter from a standard SCSI connector to that connector, if one had a Mac Portable hard drive to work from as an example. An interesting experiment might be to built such an adapter cable (Mac Portable drive to SCSI connector) and then see if you can fit a Low Profile ATA drive with an Acard 7220U adapter in there. Or better yet, 2.5 ATA drive = 2.5 to 3.5 adapter= 722U ATA to SCSI adapter= SCSI to Mac Portable adapter. I suspect that this would actually save power and weight.

I am planning on using the Newton with= my color classic. The Newt 2000 can run OS 2.1, which makes it into a 2100, effectively. Mine does. You had to send it to Apple for a ROM replacement. /Possibly/ some enterprising hacker *might* be able to do an unofficial ROM swap, but it'd be risky... Most ROMs can be replaced with EEPROM, EPROM or Flash chips which have identical (for purposes of reading) pinouts. It is very rare to find a ROM which does not have a corresponding EEPROM or flash chip. For example, I've replaced the ROMs on the x500 series of machines, the 7200 and the Power Tower Pro with Hyundai Flash chips programmed with the 9600 Enhanced ROM code. This solves the Speculative Processing issue with G3 processors. On the other hand, building a IIci ROM for the SE/30 (ahh, on topic at last) was complicated by the fact that the ROM chips used on the SE/30 module are all so old that no corresponding chips are available any more. And the Beige G3 uses a pair of bizarre 32 bit wide ROM chips with 70-something pins. For those, there is no corresponding EEPROM or Flash--or if there ever was, it went out of production so quickly it didn't leave a hint of its datasheet anywhere on the internet. So the questions to be answered are what kind of ROM is used in the Newton--anyone have an image of the ROM chip? How difficult is it to remove the ROM and replace it? I have a chip programmer, but very little interest in Newtons. If someone wants to come up with a 2.1 Newton ROM I can probably run them a few backup copies. Brian's message (see below) seems to imply that replacing the ROM is not unthinkable. So we may be able to increase the supply a bit. It is at least worth looking into, it seems. The difficulty for most folks will probably be that once they have their hands on one ver. 2.1 ROM, they won't need any more, so rather than run copies, they'll just install it in their Newton. :-) Spare ROMs are made of unobtainium but you can transplant one from a dead MP120/2.0 if you get one on ebay or whereever.

Re: 512 Plus RAM change?
Date: Wed, 20 Jul 2005 15:25:32 -0700 Subject: Re: 512 Plus RAM change? From: [EMAIL PROTECTED] From: J.B. Troost [EMAIL PROTECTED] Is it possible to use the SIMMS in a 512 for a Plus and if so how do I dismantle the logic board of the 512? The board of the Plus is no problem, but a small board prevents the thing from sliding out the case. No. The RAM chips in the 512k cannot be used in a Plus. They are easy to remove from the logic board, however, just desolder, but they will only be good on another 512k or a 128k (w/minimux). And I don't understand the last part of your question at all. Are you talking about the RAM SIMMs that stick up at an angle at the rear of the Plus logic board? If so, you have a problem with the way they are seated or the chassis is bent. Either way, the board is designed to slid in and out easily with those SIMMs installed. It sounds as if the 512 has a daughter board on top, in which case it is not a stock 512K. Because the original poster specifically mentioned SIMMs on the 512K, my guess would be that there is actually an upgrade board on his 512K which uses SIMMs and he doesn't realize that it is not a normal part of the 512K. So Mr. Troost may have been referring to actual SIMMs in the 512, rather than the motherboard memory chips. J.B. we need to know whether there is a daughter card attached to the main board in your 512. It sounds like there is since you're having trouble removing the logic board. If that is the case, unplug the cable that attached the logic board (horizontal board) to the analog board (vertical board) and unplug the floppy cable. Then turn the machine upside down and using a medium flathead screwdriver, gently pry one side of the metal frame away from the logic board just enough to slip that edge of the logic board loose. The logic board is on two rails/slots which are part of the frame. You can't slide the board in and out once there's a daughter card installed. I hope that helps.

Re: Classic Analogue Boards Update
Date: Thu, 30 Jun 2005 12:30:12 -0700 Subject: Classic Analogue Boards Update From: [EMAIL PROTECTED] Message-ID: [EMAIL PROTECTED] Apparently Samsung made the earlier board and Hitachi made the later board. Possibly they redesigned it for the Classic II and then moved all the Classics to the new one when the Samsung contract was finished. I think I mentioned this once before a couple of years ago... While Googling on the Samsung part number for the CRT I came across an interesting part. It was a CRT (same part number) and deflection(?) board for black and white security monitors. I ordered a few (brand new CRTs, woo hoo!) and was surprised to discover that the attached circuit board is very very similar to the analog board on a Plus. I haven't traced a schematic, but many of the major components found on a Plus board are also on this board, including the BU406 and the 3.9 UF non-polarized cap, etc. So I didn't just get CRTs for my money (which is nice since I paid a bit more than I wished) but also flybacks, BU406s, etc. It may be similar to the SE board as well. I mention the Plus because that's what I'm familiar with. I've never had an SE and only recently bought a couple of SE/30s. So, Samsung was selling a board very similar to the Plus analog board for BW video monitors. Which makes me wonder if Woz or whoever, got the design for the video portion of the analog board from a Samsung White Sheet, or just took a security monitor apart or what. I wonder what the engineering design connection was. Jeff Walther -- Compact Macs is sponsored by http://lowendmac.com/.

Re: SE Cleanup

I have enough SE's, SE/30s and motherboards thereof with The last time I was in Fry's they had the 1/2AA battery with leads on the ends instead of contacts. Assuming that's the type of battery installed in the older version SE, etc., then there's no reason why one can't leave the machine in original condition and still have a working battery.

Re: Classic II Sound Problem
Date: Wed, 22 Jun 2005 18:31:16 -0700 (PDT) From: Scott Baret [EMAIL PROTECTED] If you are ever offered a bunch of Classics (or any old Mac), just take them all. The University of Texas at Austin was one of Apple's largest single customers back in the early days. They sell surplus equipment at auction here in Austin. Unfortunately, the ledge changed state law about five years ago or so, directing surplus computer equipment to the corrections department. Before that, at every auction (2 or 3 times a year) there would be a couple of lots made up of 20 or 30 classic Macs. When I first started going it was 128Ks and 512Ks and if there was a Plus or SE in the lot, it was a big deal. By the time the law changed it was starting to include some SE/30s and a few Classics. Unfortunately, the keyboards were always in a big bin/lot with the PC keyboards. The auctioneers apparently didn't know there was a difference or didn't care. Those lots never went for all that much, as I recall, but I never bought one because I didn't have room to store all those machines, unless I gave up my bed. And I figured that I could always pick up a lot of them at the next auction. Sigh. Now, if I want a new classic, I'm reduced to hunting Ebay for auctions originating in Austin, because I don't want to pay the shipping. There's probably two or three folks in town with a garage full of the things wondering what to do with them, assuming they didn't all end up at the recyclers. Does anyone have any experience with contacting recyclers to see if they'll let one browse their stuff? My guess is that they just wouldn't want hte hassle/potential liability of someone in their work/warehouse area. But I have this vision of Macintosh treasure headed for smelting. Of course the reality is probably 99% PC junk with a hard to pick out 1% Mac treasure mixed in. Then again, folks occasionally mention their finds at the landfill. How does that work? I imagine it would be very hard to pick out anything from all the rotting furniture and vegetables. Jeff Walther -- Compact Macs is sponsored by http://lowendmac.com/.

Re: Classic II Sound Problem
From: Jan Warreyn [EMAIL PROTECTED] Date: Thu, 23 Jun 2005 20:14:40 +0200 The problem with this option being that all these parts are equally old... and if the built-in obsolescence theory holds true*, they should all succumb quite soon. Too bad that there is no way of ascertaining wich caps are responsible for this particular failure. If this info were available, it would be simple enough to replace the faulty caps with brand new ones... wouldn't it? Jan It really isn't that big a deal to just replace all of them. There usually seem to be about 20 of them. If you use Tantalum replacements they'll cost about $.50 - $1.00 each depending on what brand and series you buy and if you have enough boards to justify buying 100. If you replace them with the original type, electrolytic cans, then they cost about $.16 - $.25 each, but you're likely to be replacing them again in five to ten years. This page http://homepage.mac.com/schrier/mhz.html has some info on this kind of soldering, though you may have to read through a bit of stuff to get to the soldering tips. It's about surface mount resistors, which needed to be moved in some clock chipping operations, but it is aimed at folks who may not have done that kind of work before. And soldering surface mount resistors is pretty much just like doing capacitors. If you're in the US, you can get a pair of 15 watt grounded soldering pencils at Radio Shack for under $10 each. Add a small disk of desoldering braid, say .050 wide, and some 60/40 solder in a thin guage and you're equiped for well under $30. You just let the soldering pencils heat, take one in each hand, and apply to each side of the capacitor until it lifts off the board with little resistance. Then clean the pads with the desoldering braid, place the new cap (paying attention to polarity), and solder it down one side at a time. As one of my lab instructors told me, if you drop a soldering iron, let it fall. Don't try to catch it. :-) Does anyone have some pointers regarding the different types of capacitors available--Professor Lee, perhaps? Within a category and manufacturer, such as Kemet or AVX made tantalum capacitors there will usually be four or five categories with different qualities such as low-ESR, etc. Should we just go with the lowest priced one, or do some of those qualities matter for our applications.

Re: Opening up a 400k drive?
Date: Mon, 20 Jun 2005 20:26:00 -0400 From: Russell Shannon [EMAIL PROTECTED] I have just purchased a 400k drive off of eBay with the thought of offering it up list members, many of whom contacted me in past months to say they were looking for 400k drives. However, it seems to have arrived partially DOA. It's in great outward condition, powers up (the red LED comes on) but I cannot physically insert a disk all the way in. Could the mechanism be stuck in the down position? I tried opening it, but the screws are some funky kind of flat-head. What kind of screw driver do I need to open an Apple 400k drive? Back in the mid-90s I received a couple of brand new, still sealed, 400K drives in a lot of Apple Service Parts I bought at auction. It's been a long time so my memory is hazy to the exact details, but the drives had a similar problem. I couldn't insert a disk. The problem was that the lubricant on the mechanism had turned to glue over time. The solution was not disassembly. All I had to do was gently clean off the lubricant residue with rubbing alcohol (if you can get the 95% stuff at your grocery, that's even better) and then very sparingly apply some lithium grease or light machine oil to the areas where I removed the residue. That fixed it right up. The second one was sold and shipped without ever examining it (it was still sealed, after all) and the buyer had the same problem and simple solution.

Sun Remarketing is interesting. They were a purveyor of way over-priced stuff.

Re: 1GB Compaq SCSI Hard drive
Date: Thu, 26 May 2005 21:57:44 +0100 From: [EMAIL PROTECTED] (Sean Billings) I've just got hold of a 1GB SCSI Compaq Harddrive and thought I would see if I can get it to work, but I can't get MacEnvy or Lido to recognise it on the SCSI bus, is there anything I can try? Some of those Compaq drives just won't work on other machines even though they may have a model number from someone like Seagate, which usually indicates a usable drive. There is something odd about some of the Compaq badged drives, especially from the era when they were sold in Proliant or Prolinea (mid- 90s?) servers. Someone once speculated that they used an odd sector or block size or some such. I could never get some of the ones I tried to work on a Mac. One thing I never tried was putting the drive on a PC with an Adapter SCSI card that has built-in drive utilities (1540CF, 2940/U/UW, etc., NOT 2905, 2910, 2906) press cntrl-A at boot to enter the SCSI card utilities and use the utility to low-level format the drive. This might make it usable--or make it unusable on any machine. I have resurrected some Mac drives this way, when my formatting software on the Mac quit or froze in the middle of a format and left the drive unusable and unrecognizable to any Mac software.

Mike Frys sells a product called Flux Off in an aerosol can. It will take stuff off of circuit boards nicely, including residual solder flux (:-). Other stores which are well equipped with solder supplies will sell something similar or the same product--e.g. Altex in Texas. IIRC it's about $6 a can, which may be more than you wish to spend on an old board. I keep it on hand anyway for my soldering projects. Really though, I think one should replace the caps when this issue arises, as well as cleaning the board. If you use the two soldering pencil method (as popularized by Marc Schrier's Clock Chipping Homepage), it's really easy to non-destructively remove those old surface mount caps.

The IIsi adapter is really not much more than just that, an adapter with only a few components on the board so I don't think it is drawing a whole lot of power by itself. If not having the cache card installed on it would cause an error is another question altogether. My PSU is the Sony model BTW. -Ralph This is kind of obvious, but you don't have the FPU chip installed in teh PDS adapter, do you?

The unit was advertised as 50 pin, but on arrival I have found it is 68 pin :( The seller has suggested he could provide an adaptor. Would this work? Has anyone used a 68 --- 50 pin SCSI adaptor? Thanks everyone! Rob Get a refund if you can. Drives can be adapted, but unless you have a good understanding of SCSI, you will almost certainly run into termination issues when using adapted drives. There is one seller (at least one) who places auctions in the Macintosh areas of Ebay and phrases it so that it sounds like you're getting a 50 pin drive, but he's really selling adapted 68 pin and 80 pin (SCA) drives. A careful reading will reveal the ambiguity, although it takes a very careful reading. His item descriptions teeter on the precipice of deceptive. I don't know if that's who you bought from and I don't remember his ID at the moment, but the Ebay item descriptions have this red and white motif. In fairness I should say that adapted drives can be made to work. But there are a number of issues with whether the adapter terminates the top and the bottom data lines, or just the top or none at all. Whether it can be switched. Whehter the drive is at the end of the SCSI chain (enable termination on the drive (top and bottom) and disable it on the adapter (don't want double termination on anything). Whether the drive is in the middle of the chain--disable termination on the drive, but enable termination of the top data byte on the adapter, if it provides this feature. Termination is a mess when you use adapted drives. Jeff Walther -- Compact Macs is sponsored by http://lowendmac.com/.

Re: What the heck is this?
Date: Thu, 03 Mar 2005 20:18:52 -0800 From: Dave Huseby [EMAIL PROTECTED] When I pulled the logic board, I was surprised to find that my 512K has been upgraded to a Mac Plus with a Sophisticated Circuits ROM/process upgrade with a Macs-a-Million memory expansion. Here's a photo: http://www.linuxprogrammer.org/512_plus_upgrade_small.jpg If the Logic chip is labeled 5380 or 53C80 then it is definitely a SCSI port adapter. I can't imagine what else it could be. That's the only thing I know of that plugged into the ROM sockets and then piggybacked the ROMs on top. The other board looks like most of the memory sockets are unpopulated. I imagine you have a bit more capacity there. How much memory does the thing have wiwth the card installed? 1 MB, 2 MB? Jeff Walther -- Compact Macs is sponsored by http://lowendmac.com/.

The difficulty there is that they have a $5 surcharge on orders under $25 (and the caps won't cost $25) and I think there's a $6 surcharge on international (i.e. outside USA) orders. But they definitely have the caps and also workable tantalum substitutes. http://www.digikey.com I think Gamba had a supply he was selling to list members but AFAIK no-one has heard from him in some time.

Please forgive me if I'm covering old ground, as I haven't followed this thread in detail. The repeated eject cycle symptom is caused by using the wrong floppy cable, I believe. At least I know it is in some cases. There are floppy cables with a yellow stripe and others with a red stripe and one of the two has one of the conductors cut. If you use one in place of the other (don't remember if that's red for yellow or yellow for red) the extra conductor sends an extraneous signal to the drive and the forever eject happens.

Re: Reading Macintosh ROM's
From: waynegriffin [EMAIL PROTECTED] Subject: Reading Macintosh ROM's Date: Thu, 30 Dec 2004 16:42:31 -0500 Message-ID: [EMAIL PROTECTED] I have a nice Stag PP42 EPROM programmer here and I am familiar with its operation and how to handle electronics. Have any of you ever directly read the ROMs from older Macs straight out of the chip? I have seen ways that you can get them to dump their ROMs as files onto a floppy (basilisk). But I have never inquired about how to place the physical devices in something and read them. The reason I am asking is because I have a Plus that hangs on a Happy Mac boot and I want to ask about checksum or crc from you guys. I will know if my ROMs are bad really quickly. Unfortunately, I do not have another Plus about to A - B swap them and find out. Is it possible to burn eproms and then place them on the Macintosh motherboard instead of the custom fab chips? Yes, with caveats. I have desoldered IIci ROMs, read their contents, and written them out to Flash chips in PLCC packaging in order to make a ROM module for the SE/30. Gamba did the module fabrication. It worked fine. The caveats are that you need to make sure that the chips you are using have the same pinouts as the ROM chips. This is rarely a problem if the chips have the same capacity, as the data, address, power, ground, CE and OE pins are pretty standardized for a given capacity of storage chip. However, the pin arrangement changes somewhere around 512Kbits. That is, chips smaller have one pin arrangement, and chips larger have a different pin arrangement. Ideally, you would compare the pinout of the Mac ROMs to the pinout (as shown on the datasheet) of the EPROM you are proposing to use. The difficulty with that is getting the pinout of the Mac ROM. Some of it can be traced out with a continuity meter. For example, power should connect to 5 volt connectors on the MB and similarly with Ground. You can probably get the datasheet for the 68000 still and then check which pins on the ROM connect to which address and data pins on the 68000. If you use the datasheet for your EPROM, and the Mac ROM matches, then you won't even really have any hunting around to do. You'll just be confirming that the Mac ROM does match the EPROM pinout. Also, if you use Flash, instead of an EPROM, you may need to make simple modifications such as tieing WE_ and Reset high by running a little wire from the power pin to those pins on the chip.

Like an older PC/AT style keyboard? There were adapters made for both ADB to Mac Plus and IBM pc to Mac Plus. But they were rare back when the Plus was new. I think you'd be incredibly luck to find one now. Are the specifications for the Plus keyboard protocol and the ADB bus protocol still available somewhere? With the inexpensive PALs available today, I would guess that there's a better than even chance one could whip up an adapter on the cheap, if one knew what signal conversions are needed.

Re: Asante EN/SC software on Plus: two steps back...
From: Jessi [EMAIL PROTECTED] Date: Mon, 1 Nov 2004 17:36:34 -0800 Well, I shoulda known, but that floppy won't work with my Plus floppy drive. My Plus can only read 800k disks. So I tried a workaround. I used my LC 520 to copy the files off the Asante floppy to 2 800k floppies. Went back to the Plus, copied those files into a folder on the external drive. Tried running the installer. Well, the installer can't deal with not having the exact physical floppy. It asks me to insert it. THen when I do it says the floppy is unreadable of course. Use something like RAMDisk+ to make a 1.5 MB RAM disk on your Plus. Insert the installation disk in your LC520 and use LocalTalk to copy the contents of the installation disk to the RAM Disk on the Plus. While System 6.8 doesn't support file sharing, it can mount volumes on the LC520 (assuming the 520 is running System 7 or later) using the AppleShare component for the Chooser. So you should be able to mount your 520's hard drive on the Plus over LocalTalk and if you've done something like drag the icon of the installation floppy onto your hard drive (on the 520) you'll have a folder which has an exact copy of the contents for the installation disk on the HD of the 520. So mount the 520's hard drive on the Plus desktop over LocalTalk. Copy the contents of the installation disk copy folder into the RAM Disk. Cut and paste the name of the folder as the name of the RAM Disk (the folder should have the same name as the installatino disk did). Now the RAM Disk on the Plus looks just like the software installation disk and you should be able to run the installer. Jeff Walther -- Compact Macs is sponsored by http://lowendmac.com/.

In other words, those little screens that security guards watch for hours use the same CRTs as our compacts, in at least some cases. I bought a few of them and they came with a board similar to the analog board in the Mac Plus. The same model of flyback transformer and the BU406 transister were present.

Where do I make the mistake? The machine totals 4056k of RAM, so with 1 MB soldered to the mobo and two 1MB SIMMs installed the other four must sum uo to 1MB. Left alone my weak understanding of data maths, I presume the board is something in the tradition of the banana boards that allowed you to piggyback your original 256k SIMMs on the SE in one slot for further use after an upgrade - memory was extremely expensive at the time, a 4MB upgrade for an SE was more than 2000 DM. Maybe everyone but me knows this alternative memory expansion board, but the Classic is the Compact I know the least about. If someone is interested I can mail JPEGs of the board. The chips are 256K X 4 or 256K addresses by 4 bits. Two chips on a board equals 256K X 8 which is a 256 KB SIMM.Four of these SIMMs gives 1 MB or RAM.256KB SIMMs were very common back in the late 80s and early 90s. The Mac Plus shipped with four 256KB SIMMs installed. At the time that the Classic came out, 256KB SIMMs were something between $5 each and turn-them-into-jewelry, while 1 MB SIMMs still cost close to $100. There are also Third Party Classic expansion boards that have three MB of RAM just soldered to the board and no SIMM sockets. Jeff Walther -- Compact Macs is sponsored by http://lowendmac.com/.

From: [EMAIL PROTECTED] Subject: Re: Soft rom question Date: Mon, 2 Aug 2004 21:31:03 -0500 The nature of work I do for a living allows me access to a wide variety of electronic components. I also have the ability to burn just about any chip made. I find this topic fascinating and if there really is demand for this I would love to offer my help. If you could give me a specific module form factor, rom size and maybe a few manufacturer parts numbers off the chips I bet I could come up with something. Nothing is too esoteric, If it was made Im willing to wager I can find it. I have the ROM code for the IIci stored away on disk, and I'd be happy to email it to you. To go into a bit more detail... I don't know what level of detail/complexity to discuss this, so I'll stay to a simple level. If this is too simplistic and covers already understood ground I apologize. The SE/30 ROM is 128K X 32. In other words it is 32 bits (4 bytes) wide and has 128K addresses. The ROM module achieves this by using four 128K X 8 chips in parallel. So the organization of the chips on the ROM module is 128K X 8. This is a very common capacity and organization for non-volatile memory chips (Flash, EEPROM, EPROM). The problem is that capacity and organization are not the only parameters of a memory chip. Another factor is the package. The package is the physical body in which the chip exists, and determines the spacing, placement, and organization of the metal pins, by which one connects to the chip. Printed circuit boards are built to take specific chip packages at specific locations. Even if you have exactly the correct chip, as far as functionality goes, if it is in the wrong package, you can't solder it onto the printed circuit board, because the chip's pins won't fit onto the circuit board's pads or will be arranged in the wrong order, or both. The SE/30 ROM module uses four 128K X 8 chips, but the two versions of the SE/30 ROM module of which I am aware, use either a 44 pin PLCC package, or a 32 pin SOP package. Okay, I just checked Gamba's page http://home.earthlink.net/~gamba2/os8_se30.html#SIMM to refresh my memory.Apparently there are three versions of the SE/30 ROM. One uses the PLCC44 chips, one uses the SOP32 chips and Gamba lists one with PLCC32 chips as well. If anyone, has one of this latter type of ROM SIMM, conversion would be relatively simple. I have never seen one of the PLCC32 type. (John Snook, if you've got a PLCC32 SE/30 module handy, I can supply the needed chips after all.) However, to convert one of the common PLCC44 or SOP32 types, one would need four memory chips with 128K X 8 organization and in a PLCC44 or SOP32 package. I'm not sure which of those two is more common. I would guess the SOP32 package, because it's listed in another spot on Gamba's page by itself. So the goal would be a FLASH, EEPROM or EPROM with a 128K X 8 organization and in a PLCC44 or an SOP32 package. I do not know specfic part numbers for any such chips, unfortunately. The chips on the ROM modules themselves are Mask ROMs, so their part numbers (e.g. HN62331) are not any real help. Anyway, if you can come up with a source of affordable SOP32 128K X 8 programmable chips, that would do the trick, and as I wrote above, I can supply the code files. I have no idea how many folks would be interested. Many of the folks who have an interest are already using a IIci or IIfx ROM. Jeff Walther P.S. Do you know an affordable (~$1/chip) source of WD92C32 chips? This is a Digital Data Separator in an 8 pin DIP package. I need a few because I'm trying to clone the external floppy drive for the old Outbound Model 125 (Mac clone) laptop. -- Compact Macs is sponsored by http://lowendmac.com/.

Re: Soft rom question
Date: Sun, 1 Aug 2004 17:46:45 -0700 (PDT) From: [EMAIL PROTECTED] [EMAIL PROTECTED] I have had diffiuclty finding a IIsi or IIfx rom sim to place in my SE/30. I have a IIsi, but the rom bank is blank, so it must be soldered on the motherboard somewhere. (Why is there is an empty rom slot?) In the past, I have used a program to copy the rom of a Macplus to use in a game simulator on a PowerMac (i.e., Macmame). Would it be possible to use this program to copy the rom from a IIsi and use it in an SE/30? Could that soft rom be copied onto a blank rom? Gamba (who seems to have vanished, though his website is still up, thank goodness) and I did in fact build a ROM SIMM, copying the contents of the IICI ROM to blank chips and installing them on a ROM module circuit board. This successfully worked in an SE/30. The same could be done with a IISI or IIFX It was a fun experiment, however, we ran into one significant (for us) obstacle. The ROM SIMM circuit board is ~.050 thick. The standard thickness on today's circuit boards is .063. So it's almost impossible to find .050 circuit board. In our case, Gamba filed the board down to the proper thickness by hand, which was difficult, time consuming and not anything that he wants to repeat (nor that I would like to attempt). Significant obstacles for other folks would be extracting the ROM code and getting it programmed into chips properly. In our case, I desoldered the ROM chips from a IICI board, read their contents on a chip programmer (a specialized piece of hardware) and then programmed blank flash memory chips with the contents. I also determined which data pins on the chips would connect to which pins of a ROM module. Then I sent the chips to Gamba, and he designed, etched and fabricated the ROM module board (printed circuit board), soldered down the chips and tested the assembly in a IICI (using the ROM slot) and in an SE/30. We also used a program to copy the ROM code directly to floppy (as the poster suggests above), which I then compared to what we extracted directly from the ROM chips. At first, it appeared that there were differences, putting us in doubt of the usability of the ROM extracting program. However, a later check seemed to indicate that the two methods yielded the same code, so perhaps I made a mistake on the first comparison.I'm still a little dubious about the ROM extraction program, though, in theory, it should work fine. Finally, the ROM code is interleaved across four ROM chips. So the first byte of the ROM code is stored on the first chip, the second byte on the second byte, etc. then the fifth byte is stored on the first chip, the sixth on the second chip, etc. If you extract the ROM contents using software, then you need some way to spread every fourth byte across chips. Many of the chip programmers have this ability included in their software, but it could be an issue. The primary thing, though, is that you need access to a chip programmer, to get the code onto blank chips, and you need the ability to build a circuit board that will plug into the ROM SIMM socket, hold the programmed memory chips, and connect everything up properly.

Jeff Walther - Jeff, I was wondering if I could modify a SE/30 ROM to put the chips you programmed on them? What do you think? johnsn Gamba and I considered this route, as it would tremendously simplify things. Building the circuit board was the most challenging part of the project, and simply replacing the chips on an existing SE/30 ROM would sidestep that task. For that matter, one could (presumably) find ROM SIMMs from a Mac II, IIx or IIcx and use those. Many of those machines seem to be meeting their ends. Unfortunately, the chips used on the SE/30 modules don't seem to match any of the blank chips which are available. Gamba has a pretty good pedigree of the ROM modules available on his website and none of them use commonly available chip packages. For example, the most common Flash chip is probably a PLCC32 package. This is the little rectangle with 7 X 9 X 7 X 9 pins on the four sides that sort of wrap down the side edges of the chip. None of the SE/30 ROMs used this kind of chip.IIRC, there's a PLCC44 ROM module and some kind of SOIC32 ROM module. If we could find Flash or EEPROM chips in a PLCC44 or SOIC32 package (again, if I remembered correctly) then it would be doable, but those chip packages are obsolete and no longer available, as far as we could tell. If that's not clear let me know and I'll try to explain better. Jeff Walther -- Compact Macs is sponsored by http://lowendmac.com/.

Asante Desktop EN/SC
My earlier question about the Desktop EN/SC (SCSI to Ethernet adapter) was prompted by the fact that a seller on Ebay seems to have a bunch of them starting at $.99 and mostly getting no bids. I already had the one on hand (from Goodwill) but picked up a few more. So if anyone is in the market for one for their Compact, this seller tomorrow99auctions seems to have a bunch of them and your chances of getting one for $.99 seems good. I bought five (silly, really, but it was hard to stop) and got three at $.99, one at $2.25 and one at $5.50. My maximum bid was $5.83 in each case.

Asante DT EN/SC on Mac Plus?
Does the Asante Desktop EN/SC work with the Mac Plus? The list of supported machines in Asante's User's Guide is Macintosh Classic Family; II, IIX, IIsi, IIcx, IIci, IIvx; SE: SE/30; LC Family, except PowerPC versions; Performa Family, except 631CD and PowerPC versions I'm guessing that Classic Family means Classic, Classic II and Color Classic and the Mac Plus is not supported, but I figured someone on this list would know for certain. The EN/SC has no power adapter, so it must get its power from the SCSI termination power line, and IIRC the Plus does not supply Termination Power, so it makes sense that it wouldn't work, but I am not certain.

Could it be Command-Option-double clic on the Finder/System file? At least, if you had MultiFinder disabled, you could enable it by doing Command-Option-double clic on the MultiFinder init... so maybe this is the method you're referring to. That sounds right. I haven't done it since I got a hard disk for my Plus. This feature came from the era of floppy only systems. Due to the limited room on floppies one often had different boot floppies for different applications. So to change without restarting you'd insert the new boot floppy, Command-Option double click on Finder (or MultiFinder) on the new disk. This would make the new floppy the boot floppy. You could then put away the old boot disk, stick in your data disk and go. What could be simpler. That sounds like what I remember, Antonio and Clark. Thank you. Now, the question for our original poster would be whether this would work on a system folder which is on a network volume. It was a definite boon during the floppy only era, before I could afford a hard drive. I had a Plus, no external floppy and 1 MB of RAM. When I upgraded to 2.5 MB of RAM, I found that part of that RAM was better spent as a RAM disk, where I would stash the OS and possibly the application after boot. This made the system way faster, and let me have document only floppies. Later I added a second floppy drive, got up to 4 MB of RAM and ultimately added a hard drive. But the RAM Disk and switch of active system folder stayed useful, as having the OS on the RAM disk really sped performance. Jeff Walther -- Compact Macs is sponsored by http://lowendmac.com/.

I am not aware of any trick that allows a Mac to switch boot volumes cleanly. With the early Mac 512K, one can swap from a boot floppy to an HD20 hard drive but that requires an interrupt in the boot process, similar to the mechanism for booting Linux/BSD on Old World PPC Macs. There was a key combo one could use in System 6 to switch the boot volume after the machine had booted. I may be mis-remembering this, as it has been a very long time since my Mac Plus was my main machine. But, IIRC, I could boot up with a RAM disk enabled, copy my System Folder to the RAM disk, and then do this key combo, clicking on the system or the finder file on the RAM disk and after that, I could eject the boot floppy and the machine would get all the system stuff it needed from the copy on the RAM disk. I remember reading how to do the key combo somewhere...but where is lost in the mists of antiquity. Now that I've thought about it I wish I could remember. I might want to do that again.

Re: Localtalk boxes
From: Daan Goedkoop [EMAIL PROTECTED] Date: Fri, 9 Jul 2004 21:52:19 +0200 On Friday 09 July 2004 14:46, Jacobson wrote: Does that mean that the 50V on the phone jack is no problem for these localtalk boxes, so you don't have to disconnect the phone system first? Daan, I do not THINK so Those boxes allowed to use telephony CABLING (cheap and available), But not the thelephone CABLE (where the phone signal is) I think this cabling was called 'cheapertalk' compared to the real localtalk. (please, do not flame me if I am wrong, its so long ago) So, (if I am correct) you can use the CABLES, but without the phone signal (you must disconnect the cables from the phone system) Thank you. Yet the best way to know whether it works is to try it out :-) It does work, neither the serial ports nor the boxes are blown up as the adapter seems to use two pins that don't have 50V on it. Yet when I picked up the phone during the Mac copying files, I heard a clear prprprpprpr noise, so it's indeed a better idea not to connect the localtalk boxes to the telephone. Luckily, the two telephone jacks that I use can be disconnected really easily. The noise you hear is probably caused by induction. A current in a nearby wire will induce a sympathetic current in wires nearby. The induction falls off as the square of the distance between the wires, but you can't get much closer together than the four wires bundled together in a phone cable (or the eight in an ethernet cable). When I ran my PhoneNet network on the yellow black wires of my apartment, I could hear a buzz pause buzz pause buzz on the phone when I was printing. Because of induction, it is always better to have a dedicated cable. But the beauty of PhoneNet is/was that you could do it on the cheap without installing additional cableing if your house was wired properly for telephony. You'd have to put up with some cross-talk (inductive interference) but the price was right. Telephone cables are four wires, two pairs. One pair of wires is green and red. The other pair is yellow and black. Modern telephone systems use only the green and red wires. PhoneNet adapters are configured to make their connection to the yellow and black pair of wires.So, in theory, it is possible to run PhoneNet over existing phone lines in a home or office. There are a few complicating factors. First, some installations may make use of the yellow and black wires to support a second phone line rather than running a second cable. You wouldn't want to try to use such a yellow/black pair for your PhoneNet installation. Second, obviously, the yellow and black wires of one extension must be connected to the yellow and black wires of the other extensions in order for PhoneNet to work between those locations in the house. But in the places where only the red and green wires are used for the telephone, the installer usually does not connect the yellow and black wires to anything in the junction box, because it is just an unused pair of wires. You can correct the latter problem by going to the box where your telephone wires gather and wiring together the yellow wires and wiring together the black wires. Third, some phone cables made to go between the wall jack and the phone completely lack the yellow black pair and only have the green red pair and so won't work for PhoneNet at all. This is particularly common in the six foot phone cables that are often included with modems. I once spent a couple of hours trying to troubleshoot a PhoneNet problem caused by one of these cables... LocalTalk/PhoneNet also runs great over Cat. 5 and Cat. 3 cabling and the RJ-11 plug of a normal telephone will plug into an RJ-45 jack of Cat. 5 or Cat. 3, connecting to just the middle four wires.So, if you're in a place with ethernet cabling and your computer only supports LocalTalk, it is possible to use LocalTalk over ethernet cables which are not in use for ethernet. Of course, one must set things up in the wiring closet so that PhoneNet connects to PhoneNet, etc. If one is in need of phonenet boxes it may also be worthwhile to check the non-Apple sections of computers and networking on Ebay. I saw an auction for something like 150 phonenet boxes starting at $10 or $20 a year or so ago.I doubt that happens every day, but every now and then...

If one has the Apple memory expansion card for the classic, then the same memory as the Plus and SE use will fit in the two slots on the expansion card.However, the Classic, without a memory card, just has a proprietary slot for memory expansion in which no SIMM will fit. A number of companies made expansion boards for the Classic which have all 3 MB of expansion soldered to the card, and in those cases the Classic doesn't take any SIMMs at all--just a special expansion card with 3 MB on board.

Membrane keyboards are basically three layers of mylar with conductive traces on two of the layers and holes for each key point on the middle layer.Once you get water between the layers, the thing never dries. You can unfold/separate the layers to let them dry but for some reason this doesn't work well either.

There are about 6-8 used computer stores around me, and I get my dad to frequent the Goodwill Tech Store in Austin Texas where he lives, so I get to play Comin' Up on Loot (my name for Tech Safari) constantly! Unfortunately, the Austin, TX store has stopped putting out Mac stuff. At least they had the last time I was there a couple of weeks ago.

Only, they no longer have bins for Mac stuff. I asked one of the clerks about this and he said they weren't stocking them anymore and they might be selling some of the stuff on Epay. I hope he was wrong and that this is a temporary thing. That place has always been a little strange with respect to Mac stuff. They claim to have a Mac guy who goes through the stuff. But sometimes I'd find one component of an item priced by itself in a bin, while the parts that must go with it were missing. And similar things that make me suspect that their Mac guy either doesn't get control or is missing info in some categories. And while they have a huge storage area behind the store area full of stuff, if one inquires (e.g. whether they have any Mac classics that aren't on the shelf, since they only shelve SE/30s in recent memory) if they have a type of item in back, they always say no, without looking.

They managed this because the hardware has NEVER compensated for the vertical blanking. Programs had to compensate themselves. Games had to have a VBL interrupt handler running as part of their code which would tell them when the video blanking signal hit the top of the screen so they could know when to refresh the screen buffer. If a game didn't do this, you'd get the tearing you talk about. But it was never the video card's responsibility to prevent this tearing. Hmmm. Does that mean that the portions of the Tool Box which write to the video space also have a VBL interrupt handler so that, e.g., word processors won't cause screen tearing? That is, assuming that word processors and such only use Tool Box routines to write to the screen and never do so directly. Another question that interests me, but is not critical, is how to implement QuickDraw accelleration. Apple used the Intel i860 in the 8*24GC to accelerate QuickDraw by porting most of the QD ToolBox to i860 assembly to run on the card instead of the CPU. I think lowendmac.com has a few articles on the 8*24GC, which from what I understand has a lot of compatability issues, especially with games. The Quadra on-board video circuitry was not accelerated, and was almost as fast as the 8*24GC, though it was optimized local bus video circuitry that took advantage of the 68040 architecture. Nonetheless, I would think a more compatible non-QuickDraw accelerated modern NuBus or PDS video card that's highly compatible with existing software would be more useful. The Quadra video probably gets a big boost through increased bandwidth, I suspect. NuBus was great in its day, but it was 4 bytes wide at 10 MHz with plenty of overhead per transaction. So maximum total was 40 MB/s and real performance was considerably lower.Hooking directly into the CPU's busses could double or triple that since the memory/CPU bus typically ran at from 20 to 33 or even 40 MHz. For example, the SE/30's PDS slot has a maximum theoretical bandwidth of 64 MB/s because it is 4 bytes wide and runs at 16 MHz. Nate, thank you for the great information. Do you have any idea how the ToolBox routines were diverted to the video card? I assume that the driver for the card must be loaded for this to work and some kind of software patch is intercepting the relevant ToolBox calls, telling the CPU to ignore them, and sending them to the video card, but I have no idea how that is done. And I suspect that there would be details, such as issues where the CPU gets too far ahead in execution order if the video card is running behind. Perhaps they only accelerate ToolBox calls which can't lead to those kinds of issues. I don't believe that QuickDraw acceleration must have compatibility issues. I think the problem is likely that Apple just stopped updating the drivers for the 8*24GC. For example, the Radius Thunder 24/GT or Thunder IV GX family works fine up through about OS 8.6 (and maybe later) with Quickdraw acceleration enabled and they work in 030 to PowerPC machines without any hitches I've heard about. But in this case the compatibility required is fairly limited in fact. I am concentrating solely on the SE/30. It would be nice to build a NuBus video card someday, but I suspect that the limited bandwidth in NuBus would make this a pointless exercise. We're probably seeing close to the best that can be done with the last Radius releases. I don't know that for a fact, but I suspect that it is true. Especially because the Villagetronic MacPicasso 340 which was released a year or two later than the Thunder IV GX has about the same performance. Besides, if I ever finish the SE/30 video card project, the next project will be to put an ethernet port on the thing. And if I ever do that, the next project will be to put a USB port on the thing. And if I ever do that the next project will be to put an IDE channel on the thing... That's my fantasy. An SE/30 with grayscale display, a color display out port, ethernet, able to connect to modern USB peripherals, and sporting an internal notebook size IDE drive so that drive availablility stops being an issue and heat and power requirements are reduced.

There, I see the photo of the necessary piece in order to make it. This piece is very difficult to find. Is this possible of her to manufacture oneself? Does someone possess the schema in order to achieve the installation? Could someone draw this schematic drawing? Thank you beforehand. Daniel :-) The device your talking about involves a few dozen IC's. I strongly doubt that all of these parts are still available, some of them are likely proprietary ICs and programmable logic manufactured exclusively by Micron. I suspect that Daniel lacks a crucial piece of information. It took me a little while to figure this out upon viewing Gamba's site. The card which Gamba built is not sufficient to achieve 256 levels of gray. His card is an accessory to the Micron Exceed video card which can be installed in the SE/30. So, in order to achieve 256 levels of gray one would need both a Micron Exceed video card which is very expensive and rare, and one of the cards which Gamba built which is moderately expensive but available, assuming anyone ever hears from Gamba again. Both cards are necessary. The schematic for this setup is not publicly available, you would need a reverse-engineered schematic and knowledge of PC board layout tools to re-do the board layout and have it manufactured. There were/are schematics of the Micron card kicking around. Someone was selling them on Ebay. A couple of the list members were kind enough to send me the copies which they obtained because I have some experience at designing and having built printed circuit boards. However, the schematics are not sufficient. As James surmises, one of the chips is a custom integrated circuit designed by Micron and never available to the general public, although one of the list members seems to have obtained a handful of the left over chips. Unfortunately, there are also a few other chips on board which are Programmable Logic Arrays (actually PALs) and these contain custom programming which can not be read out directly. It might be possible to determine the contents by analyzing the behaviour. But that would require obtaining a working copy of the card, removing the chips in question, without damaging them and then analyzing them. None of these tasks are impossible, but it may almost be easier to redesign the unit from the ground up. The SE/30 hardware is pretty simple if you have a strong background in computer design and hardware. The device driver software would be the difficult part, unless you are intimately familiar with programming device drivers for Mac OS. It probably would be easier or at least cheaper to redesign from the ground up, especially considering that modern CPLDs/FPGAs, memory chips and video timing chips are so much cheaper and superior to what was used/available on the older Micron card. I have made a very minor beginning by reading Designing Cards and Drivers for the Macintosh 3rd Edition and by having a lot of good intentions which are interfered with by life.However, while this book covers what is needed to interface one's card to the SE/30 (and NuBus machines in general) it assumes that one is already an expert on the type of card one wishes to build. I'm a fairly fresh EE. I have never designed a video card. I have looked around for references on the art and there don't seem to be any resources that cover the topic from a hardware designer's point of view. The specific question that gives me the most headache is how to handle the refresh of the screen data.I believe that updates to the screen image (changes to the contents of the video RAM) may be coming from the host CPU at any time. But if the video card is only halfway through drawing a screen image (the CRT has scanned half-way down the screen), one would not want to then implement an update on the second half of the screen which hasn't been drawn yet. This could result in the top half of the screen showing one image and the bottom half showing a completely different image, though only for one screen refresh cycle. In less extreme cases it just results in flickers and little starbursts here and there as on ancient CGA video systems. There are various schemes for dealing with this. One is to have two screen buffers--two sets of video RAM.But this requires twice the memory on the card (not a big problem now days), and it seems to require moving a lot more data back and forth, though I'm not certain.Another method is to only update the video RAM during the flyback period of the attached CRT.This requires some kind of buffering of incoming data or lowers performance

Tie that to +5 V, and the computer may not even know it is there. (I'm speculating here.) My thoughts were leaning towards a NuBus video card in an SE/30 too. Unfortunately, the cards I know of are about as long as the SE/30 is tall. Video cards to consider for such a lark would be the Precision Color Pro series from Radius which included the XP, XK and something else. Also the E-Machines Futura II SX. These are all 6.75 cards. Note the Pro in the Radius cards' names and the II in the E-Machine card's name. There were earlier non-Pro and non-II versions of these cards which were l. However, I think that the IIsi NuBus adapter would probably need to be rebuilt in order to get it into an SE/30. That is, one would want to pull the three main chips off and build a new circuit board fitted to the SE/30 for them to live on. The bin of the Computer Works (Goodwill Computer store) in Austin, Tx has(had) a number of IIsi adapters for $5 each. Also, there is a piggyback board for the Futura II SX/DSP which adds ethernet, though it tends to be rare and hard to find. Unfortunately, the piggy back e-net board does not work with Open Transport. Actually, it locks up the Mac while extensions are loading if OT tries to load. So it's Classic Networking only for that combo. But with an SE/30 NuBus adapter, and the Futura II SX and Enet combo one would have 24 bit color video and ethernet.It still wouldn't give you gray scale on the internal CRT. What we really need to do is to design a dual video (internal CRT and external video port), USB, Enet, IDE card to plug into the PDS slot. Then we could replace the internal hard drive with a 2.5 IDE model for notebooks, and have all those ports. We might need to have a power port on the back into which one would plug an external 5V adapter, though. SMSC sells USB and Enet controllers for embedded applications, which a PDS to a 68030 more or less is these days. So the main issues with those two functions would be interfacing the PDS slot to the premade chip and writing drivers. One wouldn't have to reinvent an Enet nor USB controller. Video and IDE would be a bit more challenging. But way back around 1990 the Outbound Laptop based on a Plus or SE had an internal IDE interface. So it's been done almost 15 years ago, when electronic resources were fewer and more expensive. Jeff Walther -- Compact Macs is sponsored by http://lowendmac.com/.

This is probably folklore, but I've heard that the data in ROM (PROM, EPROM, EEPROM?). This form of bit rot is supposed to happen on the order of 20 years. You can backup your ROM on certain models, but you'll need a special gizmo to do so. I'm not certain, but I think that true mask ROMs will last as long as any other fixed content chip. The problem (I think) comes from programmable devices. I have also heard the ~20 years lifetime. In some cases, the ROM in our machines may actually be POEPROM (Program Once Electrically Programmable Read Only Memory). In other cases they may be actual EPROM, EEPROMs or Flash (probably not Flash in a Compact). These types of chips may also have a limited content life. The good news is that there's probably a PC shop near you with an EEPROM programmer who can copy your ROMs to a few sets of EEPROMs for a modest price. Most non-volatile chips of a given size and organization have a pinout similar enough that they are compatible for reading. I hope this would fall under the allowable back-up copy of copyright law, but I'd advise not mentioning it to Apple. So a 128K X 8 ROM in a 28 pin DIP has the same pinout as most 128K X 8 EPROMs and EEPROMs in a 28 pin DIP so far as reading the chips goes, which is all that goes on while it's in a Mac anyway. The bad news is that machines like the SE/30 have their ROMs soldered on a SIMM module so the individual chips are not easily movable to an EEPROM programmer, and Apple used chip packages (size, shape, pinout) in those ROM modules which are nearly impossible to find now days. One can substitute cheap and common PLCC-32 chips but the ROM module (the circuit board) is not configured (pads misplaced) to take PLCC-32 chips. Gamba and I experimented with manufacturing our own ROM module configured to accept the common PLCC-32 chips and discovered an irritating fact. SIMMs from that era are only .050 thick. Standard circuit boards these days are .063 thick. So it is very difficult to make a compatible SIMM module for the old machines. Forget using some of the specials that circuit board companies offer and standard PCB stock will be too thick. This means that manufacturing regular memory SIMMs will also be either difficult or (and?) expensive. That is less of a concern, but it might be nice to churn out a few 16 MB SIMMs for the IIfx, or my pet desire is for some standard 30 pin SIMMs manufactured with SRAM chips for low power use in the Outbound laptop. Okay, all that blabbering about ROM and I haven't gotten to my real point. I've been told that the ~20 year life also applies to programmable logic chips. This is a much greater concern to me. Most machines have at least a few PLDs, PLAs, PALs or GALs (they're all pretty much the same thing) on board. It's usually next to impossible to extract the programmed content of these chips and if they start going there won't be any way to copy them. Does anyone understand why, ten years or more after the EOL for a product, companies aren't willing to release these kinds of details to the hobbyist community? It's not like they're ever going to use that particular PAL design again. Jeff Walther -- Compact Macs is sponsored by http://lowendmac.com/.

But, upon getting it home, I find it has 2048k in it and an 800k drive. This means it has a Mac Plus motherboard in it, right? It isn't possible to upgrade a 512k motherboard to 2048k, is it? A Mac Plus motherboard will have round mini-DIN8 serial (modem and printer) ports in the back. A 128/512/512KE will have rectangular DB9 serial ports. Yes, you can upgrade a 512K motherboard to 2048K provided it has the later ROMs. In other words, it needs to be a 512KE, not just a 512K. There are many ways to do the upgrade from piggybacking memory chips on the existing ones and adding address muxing (I'd be amazed to find that anyone managed this) to various upgrade boards that increase the memory. A 2 MB (really 1.5) upgrade board was a very standard upgrade for the 512KE way back when, and when combined with a SCSI upgrade made the 512KE about as useful as a Plus. True, it didn't have 4 MB of RAM at that point, but since the remaining 2 MB of RAM cost hundreds of dollars, most folk's Pluses didn't have 4 MB of RAM either in those days. I am a little uncertain about the requirement for the 'E' ROMs. I had a long conversation at Goodwill's Computerworks with a fellow customer who used to design upgrades for the compacts and he said that the early ROMs had a few instances where the upper memory limit was hard coded rather than set by what the machine detected at start up and that limit was something like 1 MB. If I'm remembering correctly and if he was remembering correctly, then you need the 512KE or Plus ROMs in order to do the larger memory upgrades.

Re: An Outbound on eBay
From: Derek R. Morton [EMAIL PROTECTED] Subject: An Outbound on eBay Date: Mon, 15 Mar 2004 21:28:03 -0600 I think this would qualify as Vintage / Compact since it is based upon the SE. In doing my normal evening browse of eBay, I found this little gem : http://cgi.ebay.com/ws/eBayISAPI.dll? ViewItemitem=2794652910category=4610 A pretty rare find indeed, I don't recall seeing one of these on eBay before (not really my cup of tea though being an SE/30 or later guy). They show up at a rate of three or four per year, I'd estimate. It is arguable whether this model is based on the SE or on the Plus. Outbound built them to take the ROMs from either Apple model and there's no standard keyboard connector, so you can't argue ADB vs. serial to resolve the SE vs. Plus question. I have several of them (no, none for sale). Back in the early 90's I picked up seven of them from CompuAdd's Back Dock Sale and refurbished five of them and sold them, which netted me just enough money to make the last two free for me and my girlfriend. If anyone has questions about these gems let me know. I probably know as much as anybody you can find these days. On the other hand, if someone could turn up contact information for Doug Swartz or Mike Duffy formerly of Outbound then we'd really have an expert available. I'm taking a hellish semester of classes though, so replies are likely to be slow. This week is spring break, so I only have six hours a day of homework to do instead of twelve...so responses may be faster. Jeff -- Compact Macs is sponsored by http://lowendmac.com/.

Re: SCSI termination
Date: Wed, 25 Feb 2004 16:01:19 -0800 (PST) From: [EMAIL PROTECTED] I'm guessing that either a) the external disk was terminated inside the box somehow or b) it was indeed unterminated, but your grandfather got lucky in that it did not cause noticable problems. So I got lucky on a daily basis for *ten years*? And then, coincidentally, the day I moved it to the Classic II my luck ran out? :) IMO, SCSI has a reputation as voodoo not because it doesn't work the way it is meant to, but because it sometimes works when it shouldn't. The rules for configuring SCSI are mildly complex. Often a person will misconfigure a SCSI bus but the devices work properly on the bus anyway because there's a certain amount of slack in the system. Then, one day, the misconfigured system stops working and the user takes comfort in the idea of SCSI voodoo, when it really should never have worked at all. That's a bit oversimplified as there are very rare instances when a properly configured SCSI chain does not function, and on our very old machines, we are working back at the edges of a formal SCSI specification when hardware may or may not have followed the formal specs. But SCSI mostly works as advertised. Jeff Walther -- Compact Macs is sponsored by http://lowendmac.com/.

Re: Imagewriter II good source?
Date: Mon, 23 Feb 2004 10:01:48 -0500 From: Stephen Taylor [EMAIL PROTECTED] Subject: Imagewriter II good source? Hi all, I guess the next step after I get my Plus (arriving tomorrow) and loading the OS (either from the hard drive or from Byron's wonderful and generous offer) will be to get a printer. What would a good source for an inexpensive, functional Imagewriter II be? Will I need drivers to load on the Plus to use the printer? I would search locally. The problem with buying an IWII isn't the cost (they're inexpensive now days), the problem is the shipping. Those puppies are heavy. You can search by region on Ebay, or post a WTB message to appropriate news groups specifying that you wish to purchase locally, and there may be local resources as well. For example, there's an austin.forsale news group. Your locale may have one as well. Jeff Walther -- Compact Macs is sponsored by http://lowendmac.com/.

Re: Ancient Electronics History
From: Derek R. Morton [EMAIL PROTECTED] Date: Sat, 21 Feb 2004 12:41:36 -0600 Jeff, Where you got the name Killy Clip is quite beyond me... I suspect you are talking about a DIP test clip. I happen to have one of the Killy Clips in a storage box left over from a 512KE upgrade many years ago (used the soldered on header strips instead). The word Killy is embossed on the thing in big readable letters. There's also a phone number (212-995-0560) which is out of service. It also mentions patented, so I suppose a patent search would turn it up, but I'm not sure if the on-line patents go back that far yet. Is this what you are after? http://products3.3m.com/catalog/us/en001/electronics_mfg/interconnects/ node_ZC4TPBMG3Lbe/root_GST1T4S9TCgv/vroot_29N82ZFX8Pge/ gvel_WJBK9SGCMRgl/theme_us_interconnect_3_0/command_AbcPageHandler/ output_html Thank you, Derek.That's not exactly what I was describing but that would do the trick and probably better than the Killy clip would. As I recall, the Killy clips were a bit hard to remove once installed. I have been all over 3M's site (now that you pointed me that way) and cannot find a data sheet for their test clips. The photo at the top of the page would be perfect for my application, but there's no way to determine if it matches any of the three clips they have listed. Have you found a magic link to datasheets on their site? Also, and this is almost rhetorical, why are the 32 pin DIPs so hard to find? I notice that they don't make a 32 pin version of their third category. Mouser and Digi-Key don't stock the 32 pin version of the first two models. They skip from 28 up to 40. It's strange. I think Google turned up a company called Newark that appears to have the 32 pin version but from the photo on their site, it doesn't appear to have the cable assembly shown in 3M's photo. On the other hand, I'm beginning to believe that that photo is not of anything that 3M sells. I think it must be one of their test clips with additional cabling added, so it's in a configuration that they don't actually sell but that one could build with a test clip, some ribbon cable and a couple of ribbon cable (IDC) connectors. http://www.pomonaelectronics.com/cgi-local/tundra.pl? abcd1234mode=Dcrumbs=cat=DIPsort=sort_field These guys skip from 28 pin up to 40 pin, reinforcing the, what's up with the missing 32 pin versions?Perhaps the 40 pin has the same spacing and width, so one can just use the 40 pin and let the extra 8 hang off the end? Anyway, despite my whining, thank you, Derek. Your information has put me on a track to what I need. If you do have any additional info like a link to 3M datasheets, I'd appreciate it.

Re: Killy clip vs. dip test clip
Date: Sat, 21 Feb 2004 14:35:19 -0800 From: Tom Lee [EMAIL PROTECTED] I am looking for a Killy Clip or equivalent to fit over a 32 pin DIP. ... I suspect you are talking about a DIP test clip. No, he really means Killy Clip. They were a very popular way to kludge expansion capability onto a 128/512/Plus. Horribly unreliable, easy to screw up the install.. Thanks, Tom. I'm glad someone else still has vivid memories of the Killy clip. However... You could make your own equivalent, though, by using a dip header (or a couple of them) and soldering them directly onto the pins of the 32 pin ic. Cheap and sort of reversible, but a bit more labor intensive. 32 pins shouldn't be too bad, though...I've done this lots of times for smaller chips. Works better than a Killy clip ever did. Derek's recommendation is actually better for my application than a Killy clip. I simply was not familiar with test clips. I knew they existed, but looking at the photo in the Digi-Key catalog and reading the description lead me to believe that they only provided accesible test points against which one could press a probe. I want pins (or that nifty cable assembly with DIP socket in the 3M photo on their site).Digi-Key's catalog photo is misleading (to me) because the photo of the test clip is upside down. The access pins are at the bottom and the clip is at the top.I was looking at the top part of the photo, thinking it was the top of the clip, and seeing no pins to which one could wire wrap or otherwise conveniently connect. Of course, Digi-Key doesn't stock the 32 pin version... An easily removable and movable assembly is needed in this case, so a test clip would be perfect and there are no clearance issues in this case. The upgrade that I bought for the 512KE had an option exactly as you describe. It included the Killy clip and it included a pair of 32 pin header strips (64 pins total) with a socket to space the header strips and support them. The instructions offered the Killy clip for those not inclined to solder but pointed out that it can pop loose.If one was willing to solder, the header strip assembly could be positioned over the chip and the strips' pins soldered to the 68000 pins, while the socket held the two header strips level and aligned and spaced properly. When the soldering was done, one removed the socket and voila, there were two nicely attached header strips sticking up from the 68000. Because I used the header strips, I have the Killy clip left over. The brand was the Newbridge/Newlife upgrade. They were less popular than other brands for some reason, but they had several interesting upgrades for the 128 - Plus. One interesting aspect of their 128/512 upgrade was that it had 8 SIMM sockets. You may recall that there was a period when 256K SIMMs were between worthless and about $5 - $10 but 1MB SIMMs were still $80 - $120. And many folks had a few 256KB SIMMs laying around unused. With the 8 sockets one could install two 1 MB SIMMs and six 256KB SIMMs and get 3.5 or 4 MB of RAM saving about $150 over what four 1 MB SIMMs would have cost.
