I clicked on the image in the report and it opened up a high def file which I
could zoom in on. For some reason it won't do it now but I snipped the HP 9000
E55 badge image as a record. Not sure how to post it here. The terminal badge
says it's a 700/96 terminal.

David,
Do you know if the key switches used in these keyboards are the same as
the one in the Nimitz keyboard?I have a two switches with broken
stems, that I have
Mattis, the problem you have is very common on these and HP85 keyboards and is
usually caused by one side of the square plunger cracking in a corner and
bowing out.
It's normally fixed by gently bending the affected side towards the centre of
the square. A little bit of heat from a hair dryer

An easy way to check the caps is to see what the voltage across them is like
when you put the system under load and the 'regulated' voltage drops. If
the cap voltage drops substantially, or if you get a high ripple under load,
that's a good sign the caps are bad.
You mention that the +5V holds up
From my old HP CE days you could always get black off the capstan if you used
alcohol or similar (never recommended). The key thing is it shouldn't be
sticky/gooey.
The official cleaning solution when they were in active use was water and a low
lint cloth.
