Hi AJ. Sorry for the extremely late response. I have been very busy the last months. The key to the Entrex system was the Scanner board and software developed by 2 or 3 guys at MIT as a project to complete their Master's. Without those two it was just a regular Data General mini-computer. The scanner polled each terminal for service and did it extremely fast.. Each terminal was directly connected individually. From the Entrex/Nixdorf days, all I have are a handful of terminal connectors and a Field Service book. If I can provide any helpful info just let me know. I will watch more closely. Regards, Barry

Vintage 1972 Core Memory - Motherboard Digital Computer Controls - Collectible
The title says it all. The board is 15" x 15". Would look great hanging on your wall. All that power...
BTW, as far as I know, this board does not work, so...Non-working. It is presented for the Art that it Is. 
Component side has two areas of slight oxidation. See photos. I didn't attempt to clean on the off chance that I'd do something I shouldn't. Otherwise board is very clean.
