Haha, figures.

I guess I could test them but I think I have the world's oldest oscilloscope. Not sure if I can trust it, the thing looks like something from world war II:

HAH. It probably needs more work than this mac. I'll just go ahead and do some with tantalums and some with ceramics.

Had anybody ever had to replace the non-electrolytic capacitors on these logic boards? Whats the lifespan on those?

I was a little freaked out to see that one of the electrolytics is labelled C106. There sure is a lot of little caps on the bottom of the board....
