Yes, Kitt Peak National Observatory does distribute a public
domain Forth system.  You have your choice of PDP-11 or VAX-11.
The PDP-11 runs under UNIX (V7), RSX-11M or stand-alone.
The VAX runs under VMS or Berkeley UNIX.
Yes, the VAX version was originally written under VMS and then
ported to UNIX (unfortunately I had a VMS VAX before a UNIX VAX -
had the hardware been in the other order, I probably would have
done things differently).  Both the PDP and VAX versions are written
in DEC Macro.  A combination of editor scripts and lex programs
convert it to UNIX assembler.  The systems are very fast.

The version is NOT FIG-Forth and NOT Forth-79 but far better
(of course, :-) ).  They include complete floating point and built in
file systems.  An 80-page manual is available too.
