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....

I only test PC style supplies and keep some wire-wound resistors like these

for dummy load.....
... not sure if they draw enough current to test yours.

Since a switched mode PSU needs a load to work properly, what do
people use as a dummy test load for power supplies?
an old automotive headlight.
I was so stingy, that I saved a two filament bulb when one filament
burned
out.
It no longer had a "low" beam, but the
"high" beam provided a nice load.
It
also gave some extra light on the workbench.
I forgot to mention that I have used car/motorcycle bulbs before, but I find
them a bit awkward to work with.
