Universal Laser Systems P/N 12-900-D Schematic from around 1

[Dave, I can't do that]

Hi people,

Long chance I know but if you don't ask...

I am trying to get an old Laser marking machine going and this board
is almost working, just not putting out the correct PWM voltage.

I have been assisted by John P and BW but am getting further out of my
depth.

I need a schematic for this board if it rings a bell with anyone.

Thanks
