I remember seeing a version of OS/9 68K running on an A1000 one time as well as CP/M 68k.. I thought hmmm.. what a great sorta off topic response :-D
What's nice is this wasn't through emulation. Also Atari ST emulators I have heard of, but I really mean the COMMAND LINE based CP/M 68k :-) Which neither were emulations. Now is someone ports SkyOS I might get really interested..
