Re: Hp 7475 Plotter Servo's

Alas, you have touched on the whole reason windoz took over the
desktop of the techies types.

WordPerfect came with a couple disks that allowed it to work with any
printer then on the market. My HP laserjet4 came with 6 floppies of
print drivers to work with software.

Windoz did make printer drivers obsolete and most of the people runing
PC's and windows or other GUI's don't remember the old days.

I have three of those plotters and two spare boards so I am interested
in this thread. I got all of mine at an auction with no manual and no
print drivers.

If there is a manual. I would like to get a copy.
