I remember in the Xerox DSBU lab the phrase was often used, "That's not a bug,
it's a feature!"

It's a design feature.
They burn out self-destructively, clearing the fault and signalling the loss of
cable-borne RFI suppression.

I reached out to the seller and explained that it may

idea to "just plug it in" and power it on without some knowledge to
remove the cover and make a visual inspect first.
Yes, I found the same info searching online. It's a Z80 box which can
run the proprietary O/S which Litton-Monroe furnished or C/PM.
A nice looking piece of equipment but nothing special.
The cursor key layout could have been laid out in a more user friendly way.

See the description..
Probably due to the failed film-in-oil (sometimes known as Rifa) line
filter capacitors--a very common failure and nonfatal.
My recollection of these machines is that they are a basic Z80 CP/M
box--I do have samples of these floppies in my archives.
So nothing special, AFAIK.
