When it first came out, before the Xenix port was done, it ran TRS-DOS and came with a 68000 assembler so people could write 68000 apps for it. Needless to say, there wasn't a huge response to that, so they added Xenix and made it a real product. -- Peter da Silva, Xenix Support, Ferranti International Controls Corporation.
