I bet your z80 didn't do this...

OK, I haven't seen these two Z-80 systems mentioned yet:

The DEC Rainbow, having both a Z-80 and an 8088.  I could run both MS-DOS and CP/M in a dual-boot configuration.  (OK, "dual boot" back then meant having both system floppies on my desk, but hey...)

Z-MOB, a project from my alma mater (U of Maryland), a massively-parallel computer running 128 Z-80s together.  After getting the original running, they started looking at upgrading the thing to 68000s, which should bring some satisfaction to Amigans' hearts. :-)
