Re: [CAD_CAM_EDM_DRO] Cnc PCB drilling machines z axis linear pot

When production wirewrap was the state of the art for construction
practice, they did have cnc type machines to build the boards. I
have a couple of boards machine wrapped from a computer system from
the late '70s. I saw a picture of one of the wiring machines in action once.

You can wirewrap boards into the low MHz range, but things start getting
flakey above that. Anyone know what a reasonable top-end is?
