I need to find a micro machinist who worked in the field in the late eighties who can render an opinion on the state of micro-movement technology at that time. Specifically, I need to know whether it was possible to machine an apparatus capable of moving a pen point across a glass surface in 50 micron increments along the x and y axes, raising and lowering the point before and after each movement.
