Many Mac se's with various issues

[mrbill0]

I picked up a couple mac se's at the local scrapyard. First machine i picked up was a mac se/30. It seemed to be a very expandable machine and i was pretty excited to pick it up. Sadly, upon opening it, it is practically destroyed from the battery leaking. I do not see motherboard trace damage, but there is heavy corrosion all over the board.  The slot with the roms and the rom chip is destroyed. Heavy rust on the internal metal, the machine is pretty much shot... Anyone here have a dead se/30 board I can salvage bits off of?

There were 3 plain mac se's there as well, i picked one of them up as well, it had a power supply issue. Between the dead se/30 and the se I made a working machine.

Is there any documentation around on disassembling and cleaning up the floppy drives?Both the drives i picked up are quite dirty and gummed up. I used a external floppy drive to get mac os installed as both the internal drives I got do not work at the moment.

I am debating going back and picking up the other 2 se's for parts. They both had corrosion on the motherboard as well, not quite as bad though.

Are schematics available for the motherboards?

Pretty happy I have been able to get one of the machines running, but still really want to try and get the se/30 working.

This site's wiki section has an excellent guide for cleaning up floppy drives.

Make sure to remove the battery from the SE if you haven't already.

The CRT, analog board, and power supply are interchangeable between the SE and SE/30. If you need to, you can use the power supply from the dead SE/30 in your regular SE. However, before doing that get a voltimeter. You can check the voltages for the SE via the external floppy port. There are two (or maybe just one, can't remember) pots on the side of the SE analog board that you can use to try to adjust the voltages back into acceptable ranges.
