"ZRT-80 CRT terminal board - manual, schematics, and
rom images (manufactured by Digital Research Computers)."
In the early days, most CP/M computers (S100 and
single-board) required a video terminal (video monitor /
keyboard combination). The 'terminal' attached to the
computer via a serial port.
The ZRT-80 was a 'budget' terminal - a kit consisting of a
single pcb to which one added a parallel ascii keyboard
and video monitor. As many were sold, they are likely to
turn up on the surplus market. I thought it would be a
good idea to preserve the manual/schematics etc for
anyone needing it.
