At any rate, I would appreciate any suggestions or tips anyone can offer me on getting this Centris 650 back from the grave. I'd hate to scrap it as it's a fine machine. There motherboard and power supply are perfectly clean. No dark stains. Most likely the some capacitors in the power supply or on the motherboard have given up the ghost. Examine the motherboard carefully for a slightly dark discoloration around the area where the power supply plugs into the MB. If it looks like there's a cola stain on there, then your surface mount electrolytic capacitors (look like tiny silver storage tanks) have leaked their electrolyte onto the board. If the MB caps have leaked you could have three problems. The electrolyte is somewhat conductive and can cause shorts. This is corrected by cleaning the MB. Some folks run them through the dishwasher, but I recommend a careful scrubbing with 91% isopropyl alcohol (or spray with Flux remover and scrub). A soft bristle or worn out toothbrush is good for scrubbing. The electrolyte is corrosive and may have eaten through traces, solder joints or vias (conductive holes through the motherboard) on the motherboard. If this is the case, you would need to identify the damaged area and either resolder damaged solder joints or bypass with wire wrap (for damaged traces or vias). As far as I can tell, all the capacitors are fine. I have read about the capacitor plague but I think that's been more recent and has mostly effected PC hardware. The power supply circuit boards looke clean too. And even if I could just replace the caps, I have zero skill with a soldering iron. There are about four of these caps that are important to the power-on circuitry. If those caps stop working, then the machine won't stay on. However, this problem more commonly has the symptom that the machine powers on for a moment and then turns off. If these caps are dead then you need to replace them. If you have leaky caps, you really ought to replace them all anyway, because they could continue to leak. If you use two 15W soldering pencils (Radio Shack $10 each) it is easy to remove the surface mount caps. Just apply one pencil to each side and gently lift the cap when it comes loose. I'm kind of looking for a no cost/super low cost solution as I'm a college student. Much of the Mac stuff I have is from Goodwill or sometimes people just giving their old stuff away. If I ever pick up a compatible power supply or motherboard I could plop those in. But I wouldn't want to gut a working Quadra just to revive a Centris. Alternatively, your power supply may be history. Again, the electrolytic capacitors in the supply are the most likely culprit, but this time you'd be dealing with through-hole caps rather than tiny surface mount caps. Replacing the caps in the power supply might fix it. Do you know anything about the fuse? You can use the power supply from the following Macs in the Centris 650: Mac IICX, IICI, IIvi, IIvx, Q700, C650, Q650, PM7100. Motherboards for the Centris 650 are not uncommon on Ebay and generally under $15. You can also use the motherboard from a Quadra 650 or a Q800. Your CPU chip is almost certainly still fine, so you could even get a MB with no CPU and just move it over, which might save you a bit. I like the seller, Olde Mac Milt (olde-mac-milt), so you might contact him and see if he has a C or Q650 motherboard available. Thanks very much for your help. Oops, just checked and it looks like he's in the process of moving. Jeff Walther -- Quadlist is sponsored by http://lowendmac.com/ and...

[q] Centris 650 Problems
Greetings, I was hoping someone could give me some suggestions for a sick Centris 650. I had it in storage for a while and before I put it in, it worked great. Once I took it out, however, I couldn't get it to turn on at all. It appears to be dead. I can't get the fan to come on or get a chime or anything. As far as I can tell, everything is fine. I even pulled the SIMMs to see if that would help. I also replaced the PRAM battery and nothing worked. At this point, I am at a loss. The only thing I can think of trying is to replace the fuse in the power supply. I have no idea if the fuse is blown or not (it's opaque so I can't see the filament) but I figure it's worth a try. Unfortunately, I can't find a replacement fuse around here. At any rate, I would appreciate any suggestions or tips anyone can offer me on getting this Centris 650 back from the grave. I'd hate to scrap it as it's a fine machine. Thank you. -Nick __ Yahoo! DSL Something to write home about.

Re: [q] Micronet SEIV help
Good afternoon everyone. This is not spam, just passing on a great website I came across. If you go to http://www.freeiPods.com/?r=15699682 you can sign up to get an ipod at no cost. It worked for me. Take it for what it's worth. Tim Sharp - Original Message - From: Casolai ! [EMAIL PROTECTED] To: Quadlist quadlist@mail.maclaunch.com Sent: Thursday, March 03, 2005 6:40 PM Subject: Re: [q] Micronet SEIV help I discovered why I was unable to flash the micronet seiv card to an ATTO bios. I'm glad I didn't give up, I almost tossed the card into the trash on several occasions because of all the crashes and lockups it was causing... it was driving me up the wall. I was entering the wrong hex number for the nubus slot it was in. I kept thinking the slots are numbered 1, 2, and 3. But they aren't. In my Workgroup Server 80, the top slot is 12, middle is 13, and I guess bottom is 14. So when doing a manual bios update to the seiv, I had to enter C as the hex value for the slot it was in (top one). After the update, the crashing and lockups completely stopped and the card is properly detected as an ATTO Silicon Express IV. However, the speed of the card is a LOT slower than it was before. With the micronet bios, during the few times when it ran for a while without crashing, I benchmarked the card at 17.6 MB/s sustained speed with my IBM DPSS-309170 drives. Now, with the ATTO 1.65 bios, and the same hard disks, its only getting 9.6 MB/s. I'm using the ATTO startup item, ATTO A/V control panel, and SiliconExpress control panel. Everything seems to be working fine, but now the speed is ok, but definately not great. 17.6 MB/s was killer for a nubus scsi card, and it wasn't using RAID either. I have the FWB 3.0.2 hard disk driver loaded on the scsi drives. Could the fact that the ATTO bios is not scsi manager 4.3 complient somehow be conflicting with those drivers? slowing the drives down? -- I recently got a Micronet oem version of the ATTO Silicon Express IV card on ebay. The Micronet firmware allows the card to be bootable, but is very very buggy. It causes my 840av to lock up a lot and is driving me up the wall. Speed on the card is excellent, with 17.6 MB/s transfers, but that speed is useless if the system keeps crashing. Anybody know a way to reflash the card to the ATTO firmware? I have the 1.6.5 ATTO firmware update, but when I run it, it cannot find any ATTO cards (Micronet firmware removes that name). If I tell the ATTO updater to manually update the nubus slot its in, the updater crashes... ATTO tech support gave me the cold shoulder and said they don't support old products like that anymore. I emailed Micronet, but they haven't answered, and I can't find any firmware updates on their website. If anybody has any idea's for help, I would appreciate it. Did you get that from Macguy10 or something similar? I just bought one on Ebay but it won't arrive for several days. I don't recall anything in the item description saying it had Micronet firmware though I might have skimmed over that. Anyway, if it is the same deal, I will work on a brute force hardware solution and if it works, I'll let you know. Many times these flashers will work if the Flash chip is blank, but not if it has other firmware on board. I can desolder the flash chip, store it's current contents to disk on my EEPROM programmer, erase the chip, and then reinstall the chip to see if the Atto flasher will work on a blank chip. If it won't work on a blank chip, we'll need to see if we can hack the firmware resource out of the Atto Firmware updater. Jeff Walther -- Quadlist is sponsored by http://lowendmac.com/ and...

Re: Is it really dead?
Ah, but there is no CUDA on a 475/605! So, the only way is to leave the battery out.
