Coherent was a 'clean room' clone of [[Seventh Edition Unix|Unix v7]], originally written for the PDP-11 in 1980. It was ported to run on the IBM PC in 1983 and to the [[Zilog Z8000]]-based [[Commodore 900]] in 1985. Coherent was somewhat famous for being audited by Bell Labs and was vetted to be free of AT&T code.  Despite its low price it failed to achieve any significant market share.

== Getting it to run ==
Right now the easiest way is to use [[Qemu]].  I've found that a memory size of 8MB is the best, as I had several issues with 12MB.  The fsck during boot does take a long time, so you need to be patient.
