Plotter Drive Program © 1985 Fabris, Robert.
A Blue Ram BASIC program that used a Penman plotter to draw a detailed space shuttle and a 'robot' (it's R2-D2 from Star Wars).
The plotter was connected to the Bally Arcade via an RS-232C serial input connected via the old Bally tape interface with a printer jack connection.
