    Andy’s PowerBook Problem

    I use mine as an emergency serial console for if I muck up my network kit :-) it works fairly well, and is much nicer looking than many of the alternatives.

    Reproducing the Lisa 2 Card Stack: The CPU Card

    You're doing really well here. This is great to watch and hear about.

    Unable to boot disks.

    The main thing here is that until you're pretty confident that you've got stable voltages coming out of the PSU, anything else in the system may be acting weirdly or glitchily. So while you're likely right that there are two faults here, you may find it difficult to debug the first until you've...

    Mac SE/30 with regular Mac SE front???

    Yeah, that's a far better plan...

    External LocalTalk / serial port clocks

    Ohhhh, I remember what I was asking about this for. This was a bad idea :D. I was trying to see whether I could get LocalTalk and Econet to share wiring. They're very, very similar: both FM-0 SDLC over RS422, but econet has a global clock for each network segment rather than each speaker...

    Mac IIci Error Type 7 when virtual memory is enabled

    Error Type 7 is a privileged instruction being hit by the CPU when it shouldn't be. If that were going to turn up at all, it'd make sense that it would turn up in the virtual memory code. But aside from 'this error is what I'd expect from malfunctioning VM code', that doesn't help much, I'm afraid

    Mac SE/30 Shenanigans

    It's a useful mod. Main thing to be careful of is that you need two separate 12V rails, and you need to make sure that the PSU works properly given that the load applied by an SE/30 is not what a PC PSU necessarily expects.
