    PRAM won't zap?

    I just read through a couple articles on the xlr8yourmac site (via archive.org....) that seem to confirm that the beige G3 tower does in fact use an ATX power supply and the motherboard jumper is set to PS/2 power supply... the desktop G3s are set to Mac and have a different PSU. I'd just verify that the ATX PSU of your choice has the correct connectors you're using now - some new ones don't have the older Molex/floppy connectors anymore - and if it does you should be good to go. I saw mention of the voltage regulator - I think the one pictured looks fine, the discoloration appears to be maybe solder flux and not so much leakage. There was also an issue with these years ago involving Royal brand VRMs that failed and were replaced... yours is a Raytheon so it should be fine, just keep that in mind if you run across one marked Royal.

    Performa 640CD Won't Run DOS after 52 Mb Upgrade

    Try removing the logic board, reseating everything, and cleaning the edge connector. My LC630 requires that step at least once every time I change a component, has been like that for years. I think something in the edge connector circuitry is a little flaky but once it works it will continue to work just fine.

    Yeah... I tried a variety with no success... See my previous post. I don't think I have version 5.1.6 to try but none of the others worked in both environments.

    These things seem to need to pass the memory test before a PRAM reset is allowed... Hence why it's not working on the first power cycle before you get video. That's my suspicion anyway. I'd also try removing and reseating EVERYTHING connected to the logic board except the CPU. Clean the edge connectors on any expansion cards you have installed too.

    How much RAM does it have? If it's close to the max of 768MB (I'm assuming this is a beige G3, NOT a blue & white) it may take a while for it to complete the memory check at startup... or it may not come on at all. Mine are both quirky as hell. Try powering it on normally, then after you hear the chime, hit command + control + power to force it to restart. I get video 100% of the time if mine do this.

    Dang it. I wish there was more documentation on these... or the software requirements, etc. I am sure that those of us who actually have one of these machines are few and far between - they were certainly not common - so knowledge is hard to track down. I know for a fact that I had it working at some point in the last 20 years. It's just been wiped and reloaded and had other hardware changes so often that I don't recall what OS I was running, but I really doubt I ever ran anything other than 8.1 on it for any length of time. That was my go-to OS for '040 machines and still is. I know it has to be something real simple because I'm still using the same install disks for everything that I was back in the day when this worked - it's just a matter of finding the right combo of software. I keep hoping that @Ries will log in and give us some more pointers!

    Performa 630 DOS issues.

    Well, this is quite the annoying little issue. I dug through my pile of system software CDs and found the following "Apple CD-ROM" extensions: 5.0.1 - was on a LC580/LC630 7.5 CD. Discs are not readable on the PC side OR the Mac side 5.1.2 - was on a "System 7.5 Update 2.0" CD... Discs are also not readable on either. 5.3.1 - was on a PowerMac 5260/100 CD, system 7.5.3. Discs are readable on the Mac side but NOT the PC side, same issue as before I have also found versions 5.3.3, 5.4, and 5.4.2... the latter two being what was installed during the OS 8 installation and 8.1 update, respectively. 5.3.3 was on a 7.6.1 CD and is the only one I haven't tried but since 5.3.1 doesn't work I don't have much hope. @Ries, what OS version are you running and what version of the PC Setup control panel do you have installed? I have 1.0.6. I feel like this is almost certainly a Mac OS 8 issue but maybe can be resolved with an extension version between 5.1.2 and 5.3.1 but I doubt I have it. Anyone? I'm half tempted to toss another hard drive in, load up 7.5.5, and see if it works but that will burn a whole evening and I have so few of those.

    You can never have too many storage options...

    I have a 44MB SyQuest drive in a Compact form factor case and man, it's just perfect for a single drive Plus or additional storage on the SEs and SE/30, and doesn't take up any more room on the desk. But wow, is it LOUD. Should fire up my Zip drive sometime and see if it still works. I even have the Zip battery pack for it - bet that thing's quite dead by now.
  9. Wonder if that's what's going on with my QS '02. I also have a 1.8GHz G4 upgrade in it, all was well with the original 933MHz CPU but mine shuts off in OS9 rather than OSX, and only at certain times - in Quake III...for example. I start a game and boom, powers down instantly. Guess I will be checking my PSU caps. Keep us posted with your results.

    Interesting... I will have to check and see what extension I'm running. I imagine it's newer rather than older.

    Minimum Compact Mac Value?

    Really just a case by case basis. If something needs 5 hours of my time and $30 of capacitors and will be worth $30 when it's fixed, it better be free. A nice clean item that I think I can break even on if I decide to sell off later is a good buy. Assigning arbitrary minimum values to things is an exercise in futility.

    Sorry I couldn't be of more help. Please update this if you get it working - I am just short on time for playing with old computers this time of year and won't get to it for a while but I'd like to know what the fix is... it's gotta be some little detail we overlooked.

    Power Macintosh G3 Minitower Upgrades

    Forgot to look the other night - found what I was looking for today but it's not what you are after. It's a bezel for 3.5" devices, not 5.25" ones unfortunately. Great for a Zip, Jaz or tape but not a CDROM...

    Dead Performa 475

    Bummer... I have lifted a few pads too. It's frustrating. I have not had any luck gluing them back on - the heat from the soldering iron burns off super glue instantly. May be better to try a piece of wire to where ever it goes. I've also had success just blobbing up a big pile of solder that touches whatever is left of the pad/trace. Probably not the best way to do it but it worked.

    I am pretty sure I have one... I will check my parts stash.
