-------------[copiously clipped]---------
I'm looking for an even more exotic derivative of the venerable 8051.
Does anyone know of a radiation-hardened microprocessor that has Forth
support? I need 100Krad total immunity and 10^-9 SEU (minumum) There is
an 8051 (original 40 pin-er) available that meets this spec, but I'd like
to bid something like the 80c552, with included ADC and DAC, as long as
the customer has to pay for these rad-hard parts (and add them to the
payload) anyway.
My original proposal for this application was a stand-alone FPGA, but
the customer(s) keep saying "whatif", and I'm not getting any younger or
richer by reciting "ancient truths". If a programmable "widget" is what
they ultimately feel they need, I want to be there with the best solution.
My appreciation (but not a damn dime) for any suggestions. ;->

is a Forth-engine in silicon. There are also several companies offering
8051 cores.
MPE support Forth for both the 8051 and the RTX families. Please send
me your postal address for more details.

Funny you should ask. One of the early Forth chips, the Harris RTX2000,
is available in a rad-hard version (although I don't know the exact
specs). For quite a while it was the highest-performance rad-hard chip
on the market. I think they're still available from Harris
Semiconductor. Alas, it has no ADCs or DACs.
Beyond that, I don't know -- I don't use rad-hard parts. If you can
tell me what CPUs are available that meet your specs, I can tell you
where to get Forth support for them. Or eliminate the middleman and look
at <ftp://ftp.forth.org/pub/Forth/FAQ/systems>. The folks at NASA
and Johns Hopkins APL check in to comp.lang.forth now and then; maybe
they can offer a few tips.

The Harris RTX 2010 is very rad-hard and still in production last I heard.

As far as I know Harris should still have a large (by rad-hard
standards anyway) stock of RTX2010's available in rad-hard form. My
understanding is that they are not building more, however. We just
launched a bunch on the NEAR satellite and at least one instrument now
in development will use it also. The rad-hard version of the RTX2010
is built using silicon-on-saphire and is thus immune to radiation
induced latchup. I believe it has a 10^-11 error/bit-day SEU rate in
the Adams orbit. Total dose immunity is good to 1 MRad although Harris
may no longer be willing to test to that level.
The part doesn't include A/D or D/A converters but it does have some
timer resources. The hardware interface is simple so it isn't too hard
to add external stuff. I believe Forth, Inc. and MPE both have good
Forth development systems for the chip and there is 'C' compiler
somewhere that was used apparently succesfully by a group here at APL.
However, most of our code was written using an in-house Forth system
written by John Hayes. {Marlin, I still haven't forgotten about your
request to write this up for FD -- I feel just as guilty as ever for not
getting to it:-) }.
If you need more details get in touch with me and I'll see what I can dig up
for you.
If you'd like to fund a nice clean 32-bit Forth micro call me too -- I've
got a nice one up my sleeve:-).

There is always the good ole trusty RCA 1802/1805 stuff. Slow, very
rad-hard, LMI has a Forth -- I have used it.
