Re: To some MSDOS was an major leap forward.
Really? Z80-based Unix? A 32-bit O/S on an 8 bit chip? I seem to remember that Xenix (when it came along) was a 16-bit port, and that Zilog did make more powerful chips based on the venerable Z80, but not quite as popular. All the Z80s I ever touched ran CP/M, and I'd have saved a month or so of beer money for a Unix that ran on them.
