    IIsi bus speed, overclocking/NuBus/PDS sync implications?

    I haven’t noticed any problems but I haven’t exactly put my 25MHz upgraded IIsi through a scientific ringer. Most confident the PDS Asante Ethernet card works fine, I played around with an E-machines combo display/Ethernet card that seemed to work okay but went back to the PDS Ethernet card when...

    Is there a way to run a PB100 without a functioning battery?

    I get this message on my PB 100 (no main battery, any AC adapter) that has a blown logic board fuse if it doesn’t have the three coin clock batteries installed.

    Need Disk Image/Documentation for ImageWriter II AppleTalk

    Huh, makes sense. Looking at the ImageWriter II Owner's Manual I have (copy-write 1985), page 52 says the following: “To enable the option (the AppleTalk card), set DIP switch SW2-4 to Closed.” I half expected my old manual to say nothing about an AppleTalk option but apparently it was...

    Need Disk Image/Documentation for ImageWriter II AppleTalk

    Will it need configuration? Once the card is installed I would think the ImageWriter printer would just show up in the Chooser when you click the AppleTalk ImageWriter icon (Assuming you have the physical cabling right and the extension). I don‘t have a lot of experience with pre System 7 but I...

    UMAX SuperMac C series CacheDoubler

    Yep, I guess Umax used what was readily available for their C500/C600 603 processor cards. :-)

    Performa 630 - Blown Power supply

    My dead Quadra 630 power supply didn't look quite that bad but not too far off before I cleaned it up with isopropyl alcohol and Q-tips. Capacitor C8 leaking is guts out aparently to char on the surrounding components. In my case I replace all the board electrolytic capacitors and it works fine...

    UMAX SuperMac C series CacheDoubler

    So first test has the power supply 5v trickle, as tested through the ADB port, working just fine so not sure what to look at next with the power supply other than a broad brush take-a-part and capacitor check/replacement. In parallel I think I want to figure out a way to power via an ATX power...

    Awesome you figured this out! Never give up, never surrender!

    UMAX SuperMac C series CacheDoubler

    Sigh. Recapped the CacheDoubler but no joy, even worse I get nothing with the original CPU back in now. I guess the power supply could have given up the ghost at a crappy time, need to figure out how to test it...

    UMAX SuperMac C series CacheDoubler

    Yeah... I think I am going to start with replacing all the CacheDoubler caps with tantalum 47uF/20V caps I have on hand, I see signs of leakage on at least one of the other ones (fingers crossed C1 wasn't some vastly different capacitance or voltage than the other two). I guess it could be...

    Pin slot on G3 Whisper Perch?

    Looking at my cards, I was wrong, both version of the wings cards I have use the 60-pin DAV connector. Here's a summary based on the cards I have and @DracheMitch's: Whisper 1 - 1997 - 820-0922-A External audio in and out Internal 26 pin connector (front panel? never used) @DracheMitch pic...

    Help: IDE to Compact Flash not working

    Since I have it out for other work, I'm going to try these in my UMAX SuperMac C500. Def could be be a bad adapter.

    Help: IDE to Compact Flash not working

    Yes, but historically didn't that only apply to SCSI disks and Drive Setup? Back in the day I recall no such limitations with IDE disks of that era. Later, toward the end of the IDE (now called PATA) spinning disk era I think manufactures stopped supporting some of the old PIO modes some early...

    Pin slot on G3 Whisper Perch?

    I think what you’ve circled is a 26 pin connector for some sort of audio out/control cable that went unused. I seem to recall reading somewhere that the initial beige G3s logical board setup was originally intended for mid range use, just a guess but maybe some models were envisioned with case...
