So I was having fun last night with my Apple IIe and it just died on me. I then noticed that all familiar smell of ancient technology botty burp.
So far I have found C15 on the main-board shorted.
It's an old plastic encased job, maybe a Tantalum?.
This isn't the first time that I have had to replace this very same cap(but on a different main-board not this one), but last time I salvaged it from another board.
Can I replace this and the others like this, with a bog-standard electrolytic? (I may put some Tantalums in instead if that's what they are)
I'm wondering if there could be something in my power supply that made this capacitor die? I have replaced all the electrolytics in the power supply but I find I have to power-cycle a lot because my video output sometimes moves right then left on the screen about once a second, jiggling back and forth. If I power-cycle a few times this goes away. (I am using an LCD monitor so maybe I should try to duplicate the problem on a CRT?)
