There was a development kit for Mac cross-dev on the DSP but I never was
able to obtain it. (I still have the card.)

I remember programming a C20 or C25 back in 1988
or so, using a pretty mediocre TI compiler. I recall having to look at the output not so
much for buggy assembly output, but to identify any really egregiously inefficient code.
To my recollection, those chips were pretty easy to program in assembler, and that was
pretty much necessary for any really timing critical code. (On the plus side, there was
a great in-circuit emulator, and I used the lovable BRIEF editor, by underware)
I think the 320C20 is the same underlying architecture as the 320C2xx series, and may be
supported by some older, possibly free, versions of the TI development environment, Code
Composer.
Good luck!

..possible free.. A look to the TI Website doesn't even list such old
versions that mentions 320c2x. I'll try somethingwith 320C2XX support as
you suggested.
Thanks,
