Hi Simon, Hello to the group,

this weekend I went digging for the Calcomp 1038/1039 manual and
if your plotter looks like this...

...I may have what you need. Drop me a note and I will try to
scan the schematics next week and load them onto my web
page. Did you make any progress with the plotter already?

    Best regards,


P.S. My plotter is a 1038 which has been upgraded with the
PCI/906 interface but it only has got a single pen holder. Does
your plotter have got three colors?
