Yup, I knew about that one.  The A2232 card (the Commodore multi-port serial
card) uses a 3.56MHz 4502 (magic new CMOS 6502 compatible that could be going
quite a bit faster) to manage its 7 6551 ACIAs, so that the 680x0 doesn't
get bogged down with interrupts when you have all 7 channels going at 19,200
baud.  The 6502 is, and probably will be, the home game machine CPU of choice
for some time to come -- it's in C64, Lynx, Atari 2600, Atari 800, Nintendo, 
etc.  It also makes a pretty handy microcontroller type thing, especially if
you can make them yourself :-)
