OK, that's normal. That's the control supply

computer is full of ferroresonant transformers.
Cool. So not entirely dead...
There are no door interlocks. Also, the door latches
may seem impossible
to open unless you got the tool, or know how to open them
without. Assuming you didn't get the tool, here's how:
1. Get a *large* paper clip and bend it to form an S.
2. Stick the end of the clip in the hole about 1/2 inch.
3. Move the clip to the left or right, so that the end inside the door

I used a household hammer to flatten a clotheshanger into a hook to fit
the narrow slits and pull the latch. Getting them is getting easier but
you are right that the latch design is aweful. I looked for and did not
find any interlocks for any of the four panels. One of these is covers the
breaker for the ps and the swing-out twinax jack panel.
The machine has two 8" hard disks mounted on thier sides with ends
latitudinal. They are stacked one top of each other in a sturdy rack with
some shock absorbing characteristics.
If you get the idea that the latch design on these
computers is awful,
you're right :-)
A console is not required to start it, although you can
shut down from
there.
The one thing that strikes me right away, partly
because you haven't
mentioned it yet, is the Unit Emergency switch. It must be in the Power
Enable position.
Sure have, it is the big red toggle on the left side of the machine. The
hum does not change
When you press the Power button on the front panel, do
you get a Power
Check light, or any light for that matter?
No, sometimes I think I hear a 'tick' in there but I may be imagining
things. It certainly has nothing to with pressing the power key on the
face panel. I'm supposing that the panel is dependent on other things
than the power supply given the ensybeentsy chicklet power-on button....
Maybe the big-red switch is tarfu. I can check it with my VOM. Should I
hear anything or see anything after hitting that switch? Docs seem to say
I should have a quiet machine but a live panel on which the chicklet power
key resides.
The key position is in the 'service' position which is documented to be
the full features of the machine - no impediments - used for instance to
install the OS or microcode.
If this switch fails, is it possible it is at fault for the 'no lights at
all' condition? It is one of those 'coke machine' keys and I'd rather not
have to tap it with a drill to cycle it a few times....
I was told the machine was fresh from deinstallation and was working. I've
reseated all boards (top rack had several, bottoms have covers on two
empty bays).
