A Cheap UNIX clone ?

[Brian Palmer]

In the May 90 issue of Byte, was an ad for an OS called Coherent from the
Mark Williams Company.  It claims to be "a virtual clone of UNIX" with
"a complete UNIX-compatible kernel".  You get a C compiler,text processing,
program development,admin and maintenance,Lex and Yacc, and UUCP.
It says its multi-tasking/multi-user ... does it has virtual memory?

Runs on a 286 or 386 AT w/ 10 meg of disk space. For 99.95.

This sounds too good to be true.  Has anyone bought a copy?  Would
someone care to comment.  Could this be a reasonable home UNIX system?

Thanks,
