postscript/nroff/troff for RS/6000 ?

[Still Searching]

(I haven't read these groups for a while; sorry if this is an old subject)

We need to be able to do document processing in our RS/6000 AIX environment.
It was suggested that we look into postscript.  And someone said they thought
some version of postscript supports the AT&T mm/nroff package.
Any information on this would be greatly appreciated.

Thank you,
Wayne Scott
