I reached out to the seller and explained that it may have been AC line capacitors which went up in smoke etc, and why it's always a bad 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.

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. --Chuck
