    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.

    Performa 630 DOS issues.

    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.

    PRAM won't zap?

    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.

    PRAM won't zap?

    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.

    Performa 630 DOS issues.

    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.

    Performa 630 DOS issues.

    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.

    Performa 630 DOS issues.

    Here's my autoexec and config files... not that it's going to do much good to copy them, the CD-ROM seems to be recognized on the DOS side but when I try to run dir on it, I get an error. Whatever disc I insert mounts on the Mac side. Very odd. FWIW when you install the PC drivers on the PC side, the installer creates a folder called alt_cfgs that contains autoexec.apl and config.apl that I'd think would work... but I get the same results. Error browsing to the disc and it still mounts on the Mac.

    Performa 630 DOS issues.

    I'm just curious, now that you have the DOS partition file created, could you go back to 7.5.5 and keep that file intact and use it? I know I got the CD-ROM working on mine at one point. I will check and see if I still have it configured. I know I have wiped and reloaded Windows on it a half dozen times recently and my latest attempt was to get Windows 95 installed and working correctly. There is a disk with DOS drivers on it that needs to be installed while DOS is running, did you do that? It includes stuff for sound, drive sharing, etc... and probably the CD drive too IIRC. You may also have to enable drive sharing from the Mac side from within the control panel.

    Dead Performa 475

    I would start by giving the board a very thorough wash and rinse and dry it well, and see if it comes to life. If not, recap, paying attention to cleaning under the caps you remove. It should boot with your current configuration of RAM and battery if you do the flick trick.

    QS '02 CPU upgrade issues

    Well, that worked. Fired right up, installed the Giga-meter extension for the correct CPU speed and all is well. I should have thought to try that but my spare time was short and my frustration level was high. I appreciate the help!
  20. I recently acquired a Giga Designs 1.8GHz G4 upgrade for my Quicksilver '02. I am having some issues getting it working and need some advice. I have installed the firmware update (3.01) and shut down from inside the updater application, installed the new CPU, and booted while holding the programmer's button. I held it for approximately 3-4 minutes and did not get a tone or a boot chime for that matter. I let it sit for a while powered on and never got anything more. At first I would get a steady power light but after unplugging and attempting boot, I get fans and everything turning on but no power light unless I hold it, and no video. I've tried a PMU reset to no avail. PRAM battery is old but tests good at 3.6v. Reinstalling the original CPU results in a working machine. Any ideas?

    QS '02 CPU upgrade issues

    I have not tried that, I bet that's what I need to do. The documentation is not real clear - the paperwork I got with the upgrade basically says to install the software, pop the CPU in and it'll work, and the software itself says to install the firmware by shutting down, and rebooting with programmer's switch pushed in. Nowhere does it mention having the old CPU in place, I figured the new one had to be installed of course. I will try that and report back. Thanks!

    Power Macintosh G3 Minitower Upgrades

    Sure you can, just pay attention to master/slave/cable select jumpers on the drive(s). To add to what Cory said: Rev 1 ROMs in these things do not support two IDE drives per channel. Rev 3 does for sure, I think Rev 2 does but not sure anymore. If you can find a Rev 3 ROM SIMM, you can use up to 4 IDE devices in your G3 without a PCI IDE controller. It's a super easy fix but finding the part these days might be harder than it was 15 years ago when I built mine...

    Burning CDs for Performa 637CD

    Pretty sure you can use either a comm slot (1) card or LCPDS like you’d find in an LC/II/III/475 etc, assuming your PDS slot is not occupied by anything already.

    Burning CDs for Performa 637CD

    Do you have an ethernet card in the 637? If not... they're readily available and cheap... best upgrade you can do on an old machine. Install all the TCP/IP and AppleShare stuff and you will be able to share with just about anything.
  25. Brett B.

    Performa 630 DOS issues.

    ProDOS is Apple II format... totally different from MS-DOS/FAT. I think the ONLY way to boot the DOS card is from a floppy, CD, or a partition file created by the DOS card utility.
