Please stay safe. That’s the plan. Thanks. We’ve had a fire (when I say fire, I mean wildfire and not what most folks are familiar with which are structure fires) near town yesterday and another one (a bit further away) today. So it’s picking up. To hit the expected 300 for this season, we’ll need about 2 per day! Fortunately most so far have been fairly small (20-80 acres). I know that sounds *large* (our property is 10 acres) but last year’s fire in Paradise was over 150,000 acres (~240 sq miles) and destroyed over 18,000 buildings. It is really hard to imagine the scale of the devastation. So everyone is taking this *much* more seriously now. Today’s fire had 6+ fire engines respond, 2 bulldozers and 2 air tankers respond.

Re: Grid 1537 ”Tempest” schematics
Nope - definitely IDE, had an IDE drive in it and someone just either didn't have the sled/tray anymore or just decided to do something on their own. Either way, I have several of the lines from the cable that are off the through holes for the IDE interface. I've taken photo's, made a drawing of the pinouts on the motherboard and now I'm writing down what each of the through holes are going to on the IDE cable and then will work through the process of elimination and tracing (which is not easy as the motherboard has an RF grid pattern solder layer on the bottom of the motherboard (board is 4 layer) but some time and patience with a multimeter and I should be able to figure out where all of the detached lines need to go to, there are only 5 so hopefully it won't be too much work. Still trying to figure out which chip is managing the IDE, I found which manages the Floppy. Yes, the 12v actually has a power connector line run to it for the HD power, along with the 5v and GND's... I need to redo those as well, they way they were done is not very safe. Once smart thing the person did was run the CMOS battery lines up through the media housing and used 2 AA battery holders to substitute for the CMOS battery and they tuck in very nicely nice to the storage shielding so you only have to undo the 2 back screws and life the back top section of cover off, versus complete taking the entire unit apart to get to the CMOS battery location on the motherboard. Its a very modular design, everything detaches separately, just the massive amount of shielding around everything makes taking it all apart quite the task.

I'm not sure that would scale to cover detailed pages on obsolete computers; why is a manual indexer going to cover them? Anyway, the whole 'how do we find the info' is a part of why I started working on CHWiki, once I discovered it - in addition to the usual advantages of wikis (good for collaboration, good for adding stuff incrementally), it would put all the info in one place, a 'one stop shopping' for old computer info.

The problem is not archiving, but rather retrieving the data. As a current example, I am looking for information on the Jonas Escort computers. A slight misspelling (Jonas instead of Jonos) resulted in a whole slew of graphic escort services. And spelling it properly has resulted in basically zero useful information about the computer itself. It is hard to believe the almost total lack of information on the Jonos. If the scarcity is real, it must be worth at least as much as the Apple I :). And ditto for the Molecular Computer although not as bad as the Jonos. BTW, these are two computers I'm looking at bringing to VCFMW if there is any serious interest. Instead of the search engines working to improve AI, they should be putting more effort into ESP.

Re: GW-DEC-1: A New DEC Prototyping Board
Speaking from experience from having done a few Unibus boards now (none of them available yet unfortunately) that providing a general Unibus interface on a quad board will consume a reasonable amount of the board space and limit flexibility on which driver/receiver/transceiver parts that can be used. That’s just for the Unibus drivers. If you want to actually *run* the interface then you’re talking a lot more stuff. Of course, the boards I’m doing are all SMD (with the exception of the unibus interface parts). I also have to add in 5v to 3.3v conversion. Even on a 4 layer board there’s lots of “congestion” which limits the number of parts that can actually placed on the board. :-( TTFN - Guy > On Aug 15, 2019, at 1:23 AM, emanuel stiebler via cctalk > wrote: > > On 2019-08-15 02:13, systems_glitch via cctalk wrote: >> Connor Krukosky and I have been working on laying out a new quad-height DEC >> protoboard, which can also be sheared down into a dual-height board.

And then there's things that use the same connector, but it's none of the three more common DEC buses! The need that led to the development of this prototype board is actually replacing missing boards in a VT05!

The manufacturer might still have them. https://www.griduk.com/ -Original Message- From: cctalk [mailto:cctalk-boun...@classiccmp.org] On Behalf Of Curt Vendel via cctalk Sent: Wednesday, August 14, 2019 10:49 PM To: cctalk@classiccmp.org Subject: Grid 1537 ”Tempest” schematics Hi, I’m doing some work for a friend who has one of these unicorns it’s apparently a super beefed up CIA use the laptop that wound up in Russia somehow and he got it shipped back here to the US The motherboard was modified it looks like the hard drive was on some kind of a tray going to a connector which is IDE compatible Someone had extremely poorly soldered on an IDE cable in place of the sled and over the years several of the pans of popped off and they’re not really making sense as to the solder points they’re supposed to go to. Complicating the matter is the paint outs are not just a direct staggered 40 Pin to Pin connection several of the through holes are not in use so just soldering on I had her and plug in the cable into it is not possible also the pens are staggered so that wouldn’t make it possible either. So to cut to the chase does anyone have the schematics or the motherboard pinouts for this connector so that I can do a proper soldering job and put on a clean working cable so that this laptop can vote from the IDE hard drive? --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Re: Grid 1537 ”Tempest” schematics
I was under the impression that the internal hard drive on the 1537 is SCSI and not IDE. Careful, some of those pins have +12 power for the drive on them as well.
