That series of computers had a battery that fit into the same space as
your power supply. Your power supply was made to substitute for the
battery, same contacts inside as the battery pack, but more convenient
for those who preferred to use AC power. You could, if you wanted, use
the power supply you have externally using a cable from it to the power
connector on the back. As I recall, it was a typical barel-type
connector and a straight through cable. In that configuration it would
charge the battery if you had that plugged in.

100 MB hard drive does sound large for that vintage, but it was probably
a standard 3.5" IDE drive inside and could be swapped with a larger one
than the factory supplied.

Not sure what you mean by "transformer outlet". Look on the side where
the hard drive is, right, near the back. Is there a 25 pin D-connector,
female? If so, that is for a floppy drive to connect up externally.

I doubt that the PS could fry by being plugged into AC without being in
the computer. But I can't say that I've ever tested that. You should
be able to power it up with a simple DC power supply connected to that
barel connector on the back. Isn't it labelled with voltage and current
