    UMAX SuperMac C series CacheDoubler

    I thought I'd post some pictures of the UMAX SuperMac C series CacheDoubler card I got off eBay not too long ago, there doesn't seem to be many pictures out there. The CacheDoubler has 1MB of "inline" cache running at 80Mhz, double the logic board bus speed that L2 cache installed there runs at...

    PB 5xx original AC adapter re-cap & modern replacement

    *** Originally posted 5/31/2021, reposting due to outage. Thankfully the text was in Bing Cache. *** The PowerBook AC Adapter (M1893) I got off eBay worked for about 2 days, at least I now know the "sold for parts" PowerBook 540c I got earlier works (and came with a 32MB RAM card!)

    G4 Mac Mini replacement optical drive

    My G4 Mac mini's superdrive seems to be on its last legs (CDR burns failing, weird noises...). Anyone have any hints on how to look for a replacement (CD-RW, combo or superdrive, DVDs aren't that important to me). Know any OEM model numbers? Seems like finding a non-Apple labeled model might be...

    Fizzbinn’s Finds

    So I’m thinking I got nice bonus with a rev 2 beige G3 motherboard I picked off eBay. Can anyone confirm if this Orange Micro FireWire/USB PCI card is the one that will work in my Performa 6360?

    PowerBook LCD backlight replacement

    I have a PowerBook 100 recapped (motherboard and screen) and now happily working except for a broken (as in snapped glass bulb) backlight lamp. Aside from finding/buying a donor machine has anyone had luck finding modern replacements for old powerbook backlights? Google found me these guys...

    IIci Cache Card

    I finally got around to replacing the two 22µf 25V capacitors on my IIci cache card but still get chimes of death when trying to boot with it installed. The old caps had clearly leaked but I didn’t see any other real damage they could have caused. Anyone have any better luck bringing one of...

    IIci with Maxell bomb damage

    Bought a IIci setup (including AppleColor High Resolution RGB Monitor, Extended Keyboard II, mouse, and all cables) off Craigslist for $50. Woo-hoo.  :ii:   I wonder what will be inside!

    CD-R/CD-RW drive for IDE pre OS X Macs?

    Does anyone have a recommendation for an IDE PATA CD-R/CD-RW drive for pre OS X Macs?  I’d like to replace the 24x CD-ROM drive in my beige G3 tower with one that will work in Mac OS 9 via Apple’s native authoring tools and/or Toast.

    Belkin F5U015 USB to SCSI adapter drivers

    Anyone have (or know where I can find) Mac OS 8/9 drivers for a Belkin F5U015 USB to SCSI adapter?  The manual seems to imply they existed: https://usermanual.wiki/Belkin/BelkinF5U015TpwUsersManual230843.2045899695.pdf I also wonder if these turn of the century USB to SCSI adapters used the...

    Full 68040 for Quadra 605

    Thinking about the best way to upgrade my Quadra 605 cpu to a non-LC version that will support running at 33Mhz (overclocking seems like a not to difficult jumper re-soldering project) I see see there are “XC” and “MC” versions of the full 68040 rated at 25 and 33Mhz...
