PostScript support on AIX3

[Applied Magnetics]

Where is the PostScript support on the RISC/6000 ?  An InfoExplorer
search for `Display PostScript' reveals that `we support Display
PostScript, too'.  A search for `PostScript' ferrets out more
low-level stuff.

I would expect this much:
  1) A utility to convert straight ascii files to ps.
  2) Font tables and a postprocessor for troff.
  3) A ps previewer.
  4) Instructions to configure InfoExplorer for printing.

Instead, I find this:
  1-2: nothing.  Fortunately, I have some freeware;  we'll see.
  3: A bunch of sources in /usr/lpp/DPS/examples and a few executables
     in /usr/lpp/DPS/bin.  Except for bin/copyright, I can't figure out
     what they do.
  4: Nothing serious.  Info is pre-configured and shrink-wrapped.  It
     prints graphics, but attempts to print the text articles as
     straight ascii.  Well, my printer takes PostScript only, ascii
     won't work;  besides, I want typeset output.

I hesitate to ask IBM.  What wisdom is there on the net?
