Huh? How could this be? How could a CNC control be based on a
commercial product that did not exist? Do you mean a CNC control
based on a commercial minicomputer product, rather than a proprietary
control/computer all in one? I saw a PDP-8 minicomputer used as a
CNC control in 1972 or so, and it was old, then.
