Someone posted a SunOS (NeWS) postscript previewer a while back.
There is a program called, I believe, xditview, on the X11R4
tape from MIT that previews troff under X.  Internally we have
a full PostScript interpreter which we use for various
devices, especially the DMD 630 terminal. It basically works
like a C compiler-- generic syntax/semantics front-end, then
a custom-made backend for specific devices. We could make this
a product if there were interest.  We also may make xditview
available as part of a future DWB release.
