UNIBUS Mystery Board ID

This hex-width board was found sitting in a UNIBUS backplane. It looks like
it may have more than two PCB layers. The metal handle, where the board
number is usually stamped, is unmarked; no board number is stamped there. On
the front side, top left, is "AD413A MADE IN USA". The top middle had the
"200415-03" handwritten on it, but that has been crossed out by a marker,
and "200850-02" appears beneath it. The top right has "S/N 5781"
handwritten. There are two 50-pin BERG (maybe formatted Pertec) connectors
at the front top. On the back of the board, at the top right, is "MRX42
200255-02", machine printed. A little to the left of that is "3183",

Google has returned nothing. What have I here?
