I agree too - just turn it on. At most I'd pull the covers and do a visual
inspection to make sure there is nothing clearly wrong, boards missing etc.
Like my 7104 as I collected it - the power supply was disconnected, and
there were paperclips on top of some of the boards (an attempt at
sabotage?). But that was unusual - generally a 7000 series mainframe fires
up with a few slight oddities, or the power supply goes into self-protect
tick mode.

I disagree, it either works or it doesn't. Just check the line voltage
setting is
correct (you really don't want to put 240V into a 'sope configured for
110V),
and then switch it on.
Most likely fault on these is ROM rot. Power up and nothing on the
display :(

David Partridge

The usual applies. When first powering it up, disconnect the PSU and
run it
with loads. At first don't turn >on the HV section. Once the LV seems to
work, get the HV working (everything should still be running on
loads)
