Many thanks for your time and input.
No problem... Diagnosing faults is much more fun that flamewars about
musuems ;-)
It's now onto the next project, which is a faulty I/O board in a Lisa 2/10.
I want to get that widget drive booting so I can experience the real Lisa
office suite!
I've had a quick look at the I/O board schematics on the web. It looks to
be several somewhat independant sectioms, each one (apart from the FDC,
which has its own 6504 microprocessor..) fairly simple. Do you have any
idea where the fault is?
