And the HD63C09EP kicks them both clear out of the game. Too bad Hitachi is to this day, contractually enjoined from even admitting that the new registers it sports, or the new, much faster instructions it supports are actually in the chip. Like how about a 32 bit value, divided by a 16 bit value, 39 clocks worst case? In a supposedly 8 bit cpu. Lots of little surprises in that 40 pin block of epoxy that was supposed to be a work-a- like of the Motorola MC6809EP.
