This sounds very similar to the way the dec vk100 and vt125 draw stuff, its a big accellerated bresenham line drawing system with a bunch of proms and counters and some very complex state machine logic, which is still not right in MAME yet...

It draws differently depending on which of the 8 octants the line is being drawn to (or is it from?), I never completely understood it.
