field maintenance print sets

Hmm, lucky day I guess... I got a 11/780 and a 11/785 field maintenance print set (2 different printsets) from the EE department. I'm rather surprised that I didnt notice these several years ago. Also, I saw what I swear must be a quad height pdp8 board. He wasnt sure what it was, so he wouldnt let me have it yet. He thought it might be a PDP11 board (did they make quad height PDP11 systems?). Heres what the board says: Excelan Exos 204 s/n 001993 It has a 16 pin male ribbon cable connector on the top of the board, and strange 2-part female connector in the middle of the board, sort of like a 10 pin and a 36 pin ribbon female connectors joined together so that there is a slight gap between them. some intel chips on the board are dated 1982, the board itself is dated 1984. Anyone know what this board is? -Lawrence LeMay
