Aha OK. I just picket the reasently published kit from M Barryman.
That one only has these files:

2022-03-12  14:49             1 620 aaa_readme.txt
2022-03-12  14:49            18 362 Fontmap.VMS
2022-03-12  14:49        34 507 776 GS.exe_alpha
2022-03-12  14:49        50 638 336 GS.exe_ia64
2022-03-12  14:49        46 333 952 GS.exe_x86_64
2022-03-12  14:49             2 177 showfonts.ps

I just copied GS.exe_alpha and tried. Later added the two
Fontmap.VMS and showfonts.ps into same directoy, no change.

Symbol GS is setup like this:

$ sh sym gs
   GS == "$UTIL:[GHOSTSCRIPT]GS.EXE_ALPHA"
$

A copy of that pdf2ps.com would be nice, if someone happens to have that.

Regards.
Jan-Erik.
