Just respond to all.
First to Paul S., I also have a rather hi-end Fluke meter too and I
can still use the BBC meter with an ugly display. It just didn't make
any sense for it to just suddenly develop the problem and it not go
away.
To Paul Perrey, you have the whether backwards. Southern California
is dry while North Carolina is humid.
To Amos, I live in Cary NC, which is right next to Raleigh. So I'm
kind of to the right side of the middle of the state.
To gino wong, when I removed one of the keyboards from the PCB
underneath, each key has a piece of something like foam rubber with
some kind of round very thin (like paper thin) conductive plastic
piece which when the key is pressed down, that round part makes
contact between two traces on the PCB. Those round plastic pieces
look like they had a metallic coating which has all disappeared and so
they don't conduct now. I was able to use the conductivity of my
finger to type directly on the PCB board just to type in some basic
commands. But for now, unless I can get a floppy drive working, there
won't be any point in trying to fix the keyboards. Without an Apple
II type computer, I now lose my ability to program EPROMs and test
7400 TTL and 4000 CMOS series chips.
