Dan,
I also have an AS2100 4/275 deskside, I think. If there are
useful tests that won't toast my machine, I can try to dig it out and
run them for you if it'll help. Mine also hasn't been on in many
moons, though, and I have not had a chance to get familiar with it at
all. :-( .
I assume you have access to all the documentation you want?
