Thefirst TMS320's are very limited with the really small hardware stack
that has only a few levels. No deep subroutine calls, no interrupt
cascading, no recursion. There is some Software routine published that
moves the HW Stack contents to the external RAM ..maybe a link register
would be better?
Don't know about later TMS's, for soure that got fixed fast..
I've found that a C Compiler for the TMS320C25 was available, the
TMS32020 isn't mentioned in that regard.

Hi guys,
I've got a bunch of TMS32020 and two TMS320C25 Chips and I want to play
with them a little :-)
Is the old DOS (orf VMS?) Software still available from somewhere?
(Yes, I have an VS4000-90 under the desk..long time ago since I've last
booted it, but ...simh also exists).
My 2000-vintage pick and place machine has a number of these 320XX series
DSPs in it to process camera images. I seem to recall they are a Harvard
architecture. I never did any programming on them.
