Picked it up on a whim, for dirt cheap. Came as-is, untested. With a 1541, an Atari 2600 Jr. (why, I don’t know, but whatever, I love the 2600). 1541 needs to be cleaned with holy water, as it’s acting a little odd. I already have 8 or 9 of them, so it’s not that important to fix right now.
Needless to say, it works!
It has some problems. Missing a key, a spring, and the plungers are broken. I managed to fix the tab key (needed a spring) so that it didn’t constantly tab the cursor when the machine was on. The missing key (ALT) is long gone, and I was told these keys are as rare as hen’s teeth. So It’ll probably be missing for a really long time.
Last problem (so far) and the biggest: They keyboard matrix was acting weird. I tore the keyboard apart checking continuity, swapped the 6526 chips around to rule those out. After more tracing, I found this:
Good times. The faint blue circle is the problem child. It’s not allowing EMI21 to connect with pin 3 of the CIA. Someone recommended a silver conductive pen to fix, but they’re $70 and don’t last. Another was a fiberglass pen to scrap it down to the copper and solder a jumper wire in there. I’m going my own route, and soldering a jumper on the underside of the board. That way I can’t hurt anything (like the socket).
