This is a basic documentary video of me locating and replacing a failed RAM chip in an Apple IIc, in which I make a number of gruesome mistakes but ultimately am triumphant. I recommend not attempting this kind of project unless you're experienced at soldering, have removed ICs before, and have watched a bunch of videos about repairing 80s computers, because there are plenty of pitfalls; these machines are very fragile. I turned the camera off for the trace repair process because I was frustrated and needed to concentrate, but it's about like you'd expect - I stripped a tiny piece of wire, bent it, dropped it into the holes, then pressed the new socket in so it traps the wire ends in the through-holes. The only detail that isn't visible is that the other end of the lower bodge wire had no available hole to drop into, so I had to wrap it around the appropriate leg of the neighboring IC. I did run a RAM test with the lower trace missing (it took me four tries to get the trace repair right) and the result was *RAM ZP 1 0 1 0 1 0 1 0. To check your IIc ROM version: - Boot up with no disk - Type "print peek(64447)" - Any response other than 255 means you have the RAM test feature.
