In which case you can check the +5V, +12V and -5V rails at pins on the
RAM chips.
I'll be on it as soon as I've done my chores for today and painted a couple
of doors :)
I will be very suprised if not all the RAM runs off
the same supply
rails. In other words, you only need to check the voltages at one of the
RAM chips (assuming there are no cracked tracks on the mainboard, but I
wouldn't worry abnot that yet!).
I was thinking ahead for any maintenance that'll be necessary.....to be
honest I'd be amazed if there were cracks on the board - the whole internals
are in beautiful condition. Dry joints possibly.....
cheers
