GSX
Dennette, t'aint quite true that GSX was a CP/M only product. An outfit
called "Machine Algorithms" in Boulder (CO) developed a DOS version back in
1984 for use in its rather nice R'bow specific Tektronix emulator known as
GTM-10; I still use this occasionally at home to get graphics output from
my office VAX. And there was a European (Swiss?) GOTELO game that came with
a DOS version of GSX (though with only a single driver for a medium res
color monitor) that seemed to have gone over the fence from one of the
European DEC sites — those folks did lots more with graphics than here —
and I still have a copy if anyone has a nostalgic interest…Steve
