<        I recently bought a Rom 01 GS from a friend of my brother.  The only
<problem with it is a bad power supply.

Greg;
        I have had several Apple 2e and GS power supplies that have gone
south and in every case it has been a single failed resister. The resister in
question is a 1/2 watt 100k resister that is approximately in the middle of
the power supply board. It is a kind of starting resister for the supply and
usually what happens is it probably runs hot, the reason for the 1/2 watt,
andeventually opens up. You can only measure it by taking it out of the
board. If I remenber correctly it is the only 100k 1/2 watt resister on the
supply. I would check this item first  right after making sure the fuse
hasn't blown.
