I kinda doubt that even the old HP scanners had schematics available.
However, the operation of a scanner is not too complex to reverse
I guess that we still can't get you to accept one, even for free, without
open hardware source.

I meant relative to Pentiums.

I'd be tempted to do it "mechanically", with a motor and generator.
8" drives may need 50 v 60 Hz (or a change of pulley and belt).
But almost everything else recently is rectified to DC.
Most "modern" computers just want 5VDC, 12VDC, etc.
The only electronics in the holography camera is the power supply for the
laser tube.  And since I don't have the original tube, a different power
supply is not a very big deal.
