Reset works, because it is a separate wire that sends that in the A500.

I have a couple of bare ones and J05/06 are not linked in these.

If the caps light stays on, it seems the keyboard can't reset itself properly. I'd probably just swap the 6570 and perhaps the 555 timer, but I've never had that problem myself so I have no prior experience.
