I have a friend with some of these who would like to get a full set of
data on this card. He has the handbook writeup with the jumper settings
and some other info.
Would like full disclosure, schematics, engineering info, etc.
This board is a Q bus card which has keyboard interface, and display
RS-170 video out. Generates an 80 x 25 display with refresh memory
supplying the information. Also includes an EIA RS-423 serial interface.
These are in systems which integrate small PDP 11 type systems to form
terminals, etc.
Thanks
Jim
