There is a program called LaserView that does what you want; the
publisher's name escapes me, but I think the program is available from
MacConnection.

Two caveats:

1) The software is intended as a programming environment for Postscript,
not as a casual viewing utility.  It is probably quite expensive and
would have a lot of things you might not need (like an integrated text
editor).

2) The Mac must be connected to a LaserWriter (via AppleTalk) for
LaserView to work.  It uses the PS interpreter in the printer to do the
actual imaging, then sends the bitmaps back to the Mac for viewing.

(side note: Adobe Illustrator does a pretty good job of rendering
PostScript files -- you might try opening your file in Illustrator and
seeing what happens.)

Beyond that, your best bet is to buy a NeXT. :->
