Re: [CAD_CAM_EDM_DRO] Windows and black boxes

Hi Jerry,

There are CF card to IDE adapters that would allow a DOS boot, and
automatically run a subset of a controller. IMO, the Gcode parser
should be left on the PC, and only a buffered stream of motion commands
sent to the SBC. The motion commands sent to the SBC should be
"vanilla" as possible.

The MCU.PAS (or the equivalent) module is the way to do it. Just add a
buffered comm driver routine to accept the motion commands.
