Seems I have two Macintosh PowerBook 180s: one has a dead colour screen but seems to boot fine, and the other (the one screenshotted above; yay ⌘+Shift+3 and enough room on the boot floppy …) has a lovely greyscale screen but a dead hard drive. I suspect we’re going to have to do a head transplant.
And no, I’m not having ¼-century 68030+68882 wish fulfillment one bit …
Since the 68kMLA wiki page on Capacitor Replacement doesn’t have it, and also doesn’t seem to be accepting new edits, here’s what you need to replace the leaky capacitors on a revision 2 Macintosh Classic II motherboard (part 820-0326-B):
- 2× 1 µF, 50 V rating (C9, C15)
- 3× 47 µF, 16 V rating (C3, C4, C13)
- 12× 10 µF, 16 V rating (C5, C6, C7, C8, C10, C11, C12, C14, C21, C74, C79, C106)
You’ll probably also be looking for a 3.6 V ‘½ AA’/14250 lithium battery too, as if it hasn’t leaked in the 25 years since your Classic II was made it’ll be completely flat. These can be a bit pricey and hard to find. I got one at Sayal for nearly $10.
The revision 2 Classic II board is immediately identifiable by having only two ROM sockets where the first revision has four ROMs.
