        What's wrong with it?

        Does it beep at you in self-test mode?

        I've found the self-test to be pretty helpful on those boards.

        If it doesn't, check/disable the watchdog reset circuit and see
if things get better. The ROMS, especially if they're masked ROMS,
tend to go bad on the old Atari B/W XY stuff.

        No. I've said it before, and I'll say it again: If someone
will build the switch PCB, I'll do the logic PCB. So far there've
been no volunteers. The switch PCB is NASTY, and I'm not going to get
stuck doing it too. People were talking about building a PC interface,
which I think is the way to go (unfortunately, I know nothing about using
the Serial/Parallel ports of a PC, or about writing software for PCs)
