Calcomp 1038: A0 plotter, single color. Using
huge 24V-DC servo motors for x and y. Command
language is PCI/906. This is interpreted by a
6800 microprocessor PCB (letter-size). Coordinates
are than transfered to another letter-size PCB which
contains a discrete sequencer (lots of 74xx-chips)
and the anolog server ciruitry.
I even have got the circuit diagrams for this
beast...
Best regards,
Erik.
