I'm looking at running a Macintosh Plus logic board off a Macintosh SE's analog board, CRT, and PSU, instead of the Plus's own analog board. I've cross-referenced and mapped the power and video pins between the two harness connectors.
What I want to understand is the Plus's output video signal versus what the SE analog board expects on its input — how (if at all) they differ, and whether there's anything I'd need to do to match the two up. Has anyone gone through this specific combination before, or knows enough about both boards' video/sync characteristics to weigh in?
I'm comfortable building whatever circuit is needed, so any insight into the signal differences (or confirmation that there aren't any) would be a big help.
I see some adapters out there but it's unclear if I can utilize the SE's video circuit with the Plus's logic board.
Thanks! litriSE
