|ECO tag on the bottom of the board|
|IC's between the 8 pin grouping mentioned on left side of board, and the ALU photo|
The Datum controller in the DG Nova 3 was a Datum 4091 optioned for the Diablo 30 drive.
Looks like acquiring one of those, or an emulator may be in order to gen up a working system.
|Part number 4091-NDC|

Clipping about the Datum controllers from Computer World

Bulb with neon arc.
Legend on the bulb
OSGLIM 73 NOT TO BE BURNT WITHOUT
MADE IN ENGLAND SERIES RESISTANCE
I have two of these, one with the legend unreadable In the photos below some of the bits of the legend can be made out, but one needs the bulb to actually decipher it.
