Yeah, I see the humor there... back in the day, I thought it was a hoot to run MS-DOS, Amiga OS, and Finder "simultaneously" on my Bridgeboard-equipped A2000 running shapshifter. ;-)
I always love to freak younger geeks out by pointing out I had a machine with 6 CPUs back then (of course, only 4 of them actually in use at any one time - the 68000 and 8086 would usually be disabled) of 4 difference architectures:
* 68000 + 68020 accelerator
* 8086 + 80286 accelerator on the bridge board
* Z80 controlling my SCSI card.
* 6502 variant controlling the keyboard.
These days, the RAID controllers in our servers at work have PPC's in them, and many modern hard-drives have ARM cores in them, so we're up to 3 architectures still (and one of the reasons why x86 ranks so low in number of units shipped).
