HP7470A plotter with the HP-IL interface - Richard L. Taylor - 08-02-2011
Of all the user programs written for the HP41, how come there are very few if any, written for the HP 7470A plotter with the HP-IL interface using the plotter module?

HPGL is just text, and you can write your own programs and don't need the plotter module, although I suspect it has functions in Mcode so it would run faster. There's a related topic at http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv019.cgi?read=148248 .
