I've never seen an AB Bandit, but that is fairly old, right?
How would it take a feedrate command for something like that? I'm suspecting that its going to need some sort of inverse time feedrate, as opposed to the typical ipm feedrate. It might need a special gcode to turn on inverse time feedrate. BTW, inverse time is loads of fun, because its different for every move!
First you get good, then you get fast. Then grouchiness sets in.
