    Lisa Motherboard differences

    Hi gang, I recently acquired a Lisa 2 and I'll need to replace the motherboard and probably the I/O board. I saw Will from Cay Mac doing a motherboard reload from Alexthecat123's recreated board. It looks fantastic & I'd like to try this, but my PCB is slightly different. I have a cluster of...

    Mac IIcx vs. IIci PSU

    My 13" Apple RGB Hi-Res came in yesterday & I connected it to my Iici with the GE PSU. Mac & display powered up, but I have no HDD inside at the moment. Screen was RED. Not very encouraging. I then shut down, connected my 80SC and then: NOTHING. Like the PSU died. The -12V pin spikes for a...

    HD20 Diagnostics

    Hi gang! I now have FOUR HD20's that will not mount on my two SE's & my 512Ke. I've tried System 3.1, 6.0.5, & 7.0 with & without the HD20 Boot floppy (I know my models do not require that, but I had to try every option). What diagnostic tool(s) can I use to troubleshoot these drives? I do not...

    MODE32/System compatability

    Hi gang, I am upgrading the RAM in my SE/30 to 128MB. I believe I have the factory ROM chip installed. I understand I'll need MODE32 for the Mac to recognize memory over 8MB. What Systems is MODE32 compatible with? Can System 6.0.3-.8 run with it installed, or is Sys 7.x required? For that...
