I wish I did. Whatever it was it required a lot of logic and memory. The boards are marked "Datum" and have some assembly numbers but no names or model numbers.

The "Datum" mark is going to be a positioning marker, for use during assembly.

And all lettering in the copper layer ("Datum" as well as the part numbers) will be referring to Augat's generic wire-wrap board, not to the specific circuit that was built on it. Any labelling referring to that specific circuit would be on stickers, or hand-written or printed onto the PCB, I would expect.
