It can be used as a co-processor to the 6502 on the motherboard. This leads (more or less as the night leads to the day...) to a kernel architecture in which the low level device drivers run on the '02 and everything else runs on the '816. The Apple IIe's abysmal treatment of interrupts, and the software driven floppy disk interface (all the bit-bashing is done in software so Woz could keep the chip count down.) have kept me from even dreaming of Minix on my Apple IIe, but maybe it is possible after all if the devices can be polled by the 6502... thus neatly finessing the interrupts problem. Enjoy!
