Anybody seen a troubleshooting guide for the old Diablo printers?
I have the maintenance manual but there's no troubleshooting guide.

Bitsavers has a "product description" (which has setup/install
instructions) and a parts list, if those help:

Mine powers up but doesn't print either via rs-232 or in local mode.

One of the standard suspects for anything is the power supply. In a
quick turn through the maintenance manual, this thing monitors its +5,
+15, and -15 supplies, and refuses to work if any of them are out of
range. (Paper page 2-28, PDF page 42.) The spec (paper page 3-30, PDF
page 98) says the limits are 4.9 to 5.1 V, 14.5 to 16.0 V, and -14.5 to
-16.0 V.

You can probably rig a standard ATX power supply to provide those.
You'll have to provide your own momentary SPST switch, if the printer's
switch isn't.
