So how's this for nifty? An Apple-II Plus with three different processors! Inside there's two co-processor cards, the first having a Motorola 6809E which allows me to run the FLEX operating system, and the second has a Zilog Z80 so I can run CP/M. Wahoo, an 8-bit machine than can run multiple operating systems!
