    Macintosh IIci DIP32 ROM replacement issues (SST39SF010A)

    Recently, I ordered four SST39SF010A chips and flashed them with the correct four parts of the Mac IIci stock ROM (DWORD bytes 1,2,3,4 interleaved). I inserted them to my sockets in the correct orientation and order, powered on the IIci, and got the normal speaker pop with no chimes or any...

    Macintosh IIcx slow chimes of death; diagnostic return code 0000FFFF0001.

    I recently got a scrap Mac IIcx, mostly to get its case for a different project, but still tried to clean and recap the board to see if it could boot. I did not attempt to power this logic board at all until the recap and washing/drying were all done, in case stray goo fried anything. The...

    SE/30 shows Simasi-like pattern when a PDS card is installed

    About a year ago, I cleaned an SE/30 motherboard and recapped it with tantalum capacitors. It has been working normally since then, except for one of the axial capacitors, which was not properly soldered. I got bus errors and sad macs recently, but solved them all by re-soldering the bad joints...

    Best Ethernet expansion card for SE/30?

    Hello, I have recently and successfully recapped my SE/30, and I'm interested in connecting it to my network to transfer files to it via FTP. However, I am relatively new to expansion cards for Compact Macs. What are some decent/common standard (RJ45) ethernet cards compatible with the SE/30...
