Classic II Motherboard in an SE? (Temporarily)

[Juror22]

I have a Classic II motherboard that I am trying to bring back to life (bad caps, corroded pads, vias and [possibly?] connections). I don't have access to the Classic II case - does anyone know definitively whether I can test this in an SE case? Not worried about the back fitting on it. Would the power/monitor cable to the motherboard work? I just need to work with it like this, until I can get it to where it will start up, display properly and prompt for a disk.

Thoughts? Anyone done this at some point?

I'm guessing the SCSI cable would work with the SE HD...

the floppy not so much (800 v 1.4M)

Wiring is not the same, so probaly won't work and will damage boards.

The power supplies don't match up.

In general, with compact Macs...you can safely swap the following boards (this does not factor rear housing differences or country of origin...)

128K, 512K, 512Ke, ED (any model), Plus all use the same PSU (although later models are more reliable--if you're planning on actually using a pre-1987 model of one of these and don't want to mess around with refurbishing it yourself, find a good working model from a platinum Plus).

SE, SE FDHD/SuperDrive, and SE/30 all use the same PSU.

Classic, Classic II use the same PSU, but if you're going just on analog boards alone, be aware of Revision A versus Revision B. The CRT connectors aren't the same (see the stickied thread about this). In general, Revision B boards are more reliable.

The pin-outs are reversed 24=1, 23=2, 22=3, etc.

theoretically you could make an adaptor, but it would be easier to just find a Classic or CII junker to test it in.
