PDP-8/E Board Picture Front of M885 Point Plot D/A board
This is the front of the M885 point plot display D/A board. It is used with the M869 ( 46k) point plot display control board to drive X/Y monitors like the VR14 monitor.
All the round adjustment pots on the board are to trim the D/A conversion so it can draw a straight line without jumps. The grey and blue ones in the upper right adjust board internal +-5V reference supplies.
