[Note: I haven't looked at the machine since last night, so this may
be out of date.]

Someone came into the SIPB office last night saying that w20-575-98
was wedged.  I looked at it, and it did appear to be thoroughly
wedged.  The keyboard and mouse didn't respond at all, although
unplugging the keyboard and plugging it back in caused the keyboard to
fweep and reset like normal.  I power-cycled it, and it seemed to boot
fine.

A bit later, he came back, saying that it was wedged again.  This
time, I interrupted the boot and ran the ROM diagnostics.  i.e.:

ok test-all

They appeared to succeed.  It didn't test all of the memory, so I did:

ok setenv diag-switch? true
ok test-memory

That worked.  Just for the Hell of it, I ran the full diagnostics
again:

ok test-all

At this point, the display went berzerk (lost sync, other weird shit).
I turned the machine off.  When I turned it back on, the keyboard
fweeped as usual, but the power light didn't come on, and the display
didn't appear to do anything.

So, I'd say there's definitely something wrong with the hardware.  B-)
