(Well, that depends on what you consider "UNIX" to be; some consider
those programs delivered with UNIX to be part of it, others don't.)

"ksh" is supplied in source form, so you're not restricted to "AT&T
boxes" (i.e., 3Bs, their 80*86 machines, and the like); you're not even
restricted to machines running System V - it can be built
under BSD-flavored systems, and possibly even under vanilla BSD.

It does cost about $2K-$3K for the source, as I remember, though.
