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

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.
