somehow I 'Knew" this question would come up.!

Look in the archives for Xynetics Plotter
After talking with the guys at Applied Motion Products I discovered
that this unit has linear bi-polar steppers!
The hitch is that [believe it or not] the motors are driven by 150V
8a .Originally designed and hooked to HP 3000 ,I have everything but
the computer,
Now it gets beyond me: drivers accept analog input via a d/a
converter card!that was installed in the computer[that I don't have]

Actually ,I asked the same question, why would any engineer put
analog between two digital devices?
They did,in 1987 when this unit was built.
I could run the motors with Geckos but thought it would be worth
trying to use the 150V drives as is.
