HP 7475A Plotter and HPGL Demo

Graphics improves communications says the plotter demo! We get a 1983 vintage HP 7475A from generous viewers and have it plot in glorious 6-pen color and wrangle HP-GL graphics commands from the command line.

The shuttle files are called Columbia.dwg (AutoCAD format) and Columbia.hpgl (HPGL version) and are available from my web site on this page: https://www.curiousmarc.com/computing...
