Anyone know what the original IBM PC AT Load was made of/from? This was for
the models w/out a HDD which I believe were far and in between so there
aren't too many of them around....
It gets a beif mention (with no description) in the HMS manual, but
nothign i nthe TechRef :-(
From what I can deduce it was a simple load resistor on
the +12V (not +5V)
line. That is a resistor wired to a 4 pin disk drive power plug
(to
conenct to the hard drive power cable) between the +12V pin and one of
the ground pins. I do not know the value of the resistor, that is not in
any of the manuals I've seen.
