+1 with Marc. Sounds like a 21MX of some flavor. It will have two
prominent card-edge connectors side-by-side around mid-board that connect
to memory and I/O busses that run "up" from the PCB-face.

They have only been used so far on the genuine DEC systems

The cause of my panel chipping is very much finger contact at the edge of the
cut panel. There is the decay starting at the edge above all the switches and
it is worse above the "deposit" switch.
The rest of the panel other than these edges seems properly intact, but I am
worried about sealing
