RE: [CAD_CAM_EDM_DRO] Re: Hp 7475 Plotter Servo's

Hi Dave,

I HAVE a manual, and actually looked for it last night. No success! But it
can't be far away from a particular book case. Just lotta stuff ALSO on the
shelves in front of the books...

I remember a lot of driver disks to fool with. I also enjoyed writing
directly to my plotter. My main commercial software product at the time
that used the plotter was CadVance (DOS), which had a driver for quite a few
printers and plotters.

Have you ran one or more of the plotters? We should be able to work out the
setups again.
