The only language I'd rally like to learn is Spanish :-)

But seriously, I do not want to get too involved in the actual
programming job because I am fully loaded with analog/mixed projects
already and want to reserve at least a few hours per week for mountain
biking.

Problem is, there is no Forth community out here. The last die-hard
Forth aficionado I personally met was about 30 years ago in Europe.

Not on this project but otherwise, yes. One of my designs containing an
8051 will celebrate its 20th next year. Still in production and no end
in sight. Second source is another concern and you can only get that for
a small selection of 8051 uC.

For other projects it does. We need to make sure that 10 years down the
road it will be possible to find someone locally who can re-write the
code. With 8051 that's usually not a problem.

Yep, near Hwy 50 just before Placerville. But the project is already
committed to a local guy if he feels comfortable to do it. Which I
should know by tomorrow. It has to be local in this case.

Can't reveal too many details but from a code point of view essentially
several FFTs, one of them a big one, 1024 point complex (I/Q) every
5msec, overlapping. Extract phase, some complex-conjugate math to
extricate component values every 5msec (sort of a poor man's reverse
network analysis), followed by filtering, some more math or a LUT, then
modulating the result onto an audio carrier. Sprinkled with user
interface handling and calibration routines. Back of the envelope calcs
indicate that this will reasonably fit into a 100MHz ARM but of course
I'd rather have a few more megahoitzes.
