Hi folks,
I have an HP 85, that I believe needs a replacement CPU chip.
There was a power supply fault caused by a misaligned flexible cable, which I
managed to repair. But, now the machine won't boot, and the CPU chip gets
very hot with 2 or 3 seconds of turning it on. I think there may be an
internal short, but I really need the schematic to know which leads to take
resistance measurements at to verify this. Does anybody have a copy? Also,
are there any people still carrying parts for this machine? I'd prefer to buy
a replacement CPU if possible rather than cannibalizing another machine.
