I was going to say that this sounds like an 80 column

later you tell me it is. That manes you don't have a cassette interface.
The syutrm firmware ROMs are also different, I don;t know if they requrie
an FDC (or other boards) to be rpesent.
If I get a voltage from the floppy connector I'l reassemble the whole
machine as was when I photographed it.
You have removed the seires bulb now, I hope. I doubt
the machine would
run with a bulb in seires with it.
Ah. I kept it in when I reassembled the basic machine, should've
realised. Will take it out tomorrow, If for nothing else I'd like my
bedroom light back :)
You only have one multimenter? What about a
'scope?
I have 2 multimeters, but one of them has a dead battery. I can borrow
a scope from work if needs be. I also have a logic probe and pulse
generator that I'm teaching myself to use (slowly) with a working and
non-working PET2001...
Cheers!
