Hmm ... I have a couple of beebs with suspected RAM faults, and I've
wondered before: is there a simple BASIC routine I can try that will
highlight faults at certain addresses, so I can track the fault down to a
particular RAM IC? Or if not a BASIC program, then something I could get
put on a sideways ROM to install in suspect computers?
