i wonder if anyone's made an efficient converter that changes G-Code to pen plotter-oriented HP-GL yet.
my last attempt using my 7550A resulted in my "fastest plotter ever made" being absolutely dog slow because it had to skip all around the page to deal with innumerable unsorted line segments, with no use made of the built-in chorded curve drawing commands or anything else of that nature
...I wonder how hard it'd be to replace the thing's drive electronics with something with more horsepower than a 68000, and whether the encoder hardware is up to continuous servocontrol for actual curves instead of decomposing them into straight lines
