    Macintosh LC475 upgrades

    Overclocking it will help.  It made a dramatic difference on mine.  You will not find any benefits from additional memory other than bragging rights.  As Cory said, a VRAM upgrade would be nice if you don't already have it. Outside of those things... realistic expectations of what it is capable...

    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...

    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...

    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...

    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...

    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...

    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...

    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...

    Quicksilver shuts itself off only under OSX

    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...

    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...

    Performa 630 DOS issues.

    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...

    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...

    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...

    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!
