- If it was in position C15, then it would have to be a Capacitor. (I
- don't have a c64, I've got a c128.. but I checked the labeling (I've got
- relatively extensive electronics knowledge... at least enough to identify a
- component.)
- From what you can tell of the component.. was it basically disklike?
- bulging in the middle, with the two parts that connect it to the board
- being approximately 90 degrees away from each other?
- I checked in MY computer, and there are both blue and light brown
- ceramic disc capacitors... Hey, even found a position C15, but it is
- probably different on the c-128. And I can't see the identification marks
- on it anyways. (I'd need a small mirror.. maybe like what a dentist uses to
- see it.. and then it would be harder to read backwards.)
-
- You would need to know what size (measured in Ferads <sp?> ) the
- capicitor was to replace it... luckily those disk capacitors are
- non-electrolytic. (you can stick 'em in either way.)
