I made the P21Forth ROMs free at my site last month for anyone 
playing with Dr. Ting's P21 boards.  The S21 simulator
(for P21) has included a version of P21Forth that runs with drivers
for the simulator.  They all include a set of CORDIC sin/cos functions
that were contributed by Dr. Michael Montvelishsky.  At the time he
did it I think it ran 50x faster in P21Forth than in FPC with an
80387 math coprocessor.  I can also post the source code to the
CORDIC and mixed math stuff.  I did not post the P21Forth source
or meta compiler.  The user manual has a section that
covers it and it has always been available online.

Machine Forth? Simulator and Emulator compatible? ;-)
