I gave up on capacitors for now. The Classic II board is probably ruined.

Now I am working on, what I believe is an original 128K (I can't tell if it's a 512K or not.)

The 400K drive was all seized up. I lubricated some of it and now it's moving, but there is this one little metal bit that refuses to slide up and down, which has something to do with keeping the disk in and the whole thing pressed down so it can read the disk.
