If you are going to get so silly as to count the keyboard processor (a mask programmed microcontroller which won't ever run anything but a few bytes of keyboard scan code) then you might as well count all the CPUs. Here are the ones on my system right now: One 68000, one 6501, one 6303, one 8048, one 8080, and three Z8's. The first two are in the Amiga, then the printer, a tape unit, a tape controller, the modem, and the hard disk (it has two Z8's). Eight processors, of six different architectures, all running code at the same time. I'd include an 8031 too but the homemade box using that isn't hooked up right now... My CP/M box has two processors in it (both Z80). And my C64 system, for a while, had 4 - computer, disk drive, printer, and the printer interface. So multiple processors really isn't such a big deal, is it... Just being obnoxious. Markus Wandel mwandel@tiger.waterloo.edu (519) 884-9547

Just being silly, but anyone remember Cromemcos with a z80 and a 68000 sharing the buss? It was neat. When you ran a program, the Cromemco would find out what kind it was by checking for a magic number and then run the code on the appropriate processor. It would simulate CP/M and had its own (loosly speaking) "Unix (tm) like" operating system. It was a really neat machine...fast too! Patrick Horgan phorgan@cup.portal.com
