It's just peachy. ;-)

I've done a couple of projects with Aptronix system, using Motorola
micros. One of the few, from what I can tell, who have both used it and
compared it realistically to other tools. '94 was about the peak of the
fuzzy mania. If no-one's mentioned it yet, the reigning god of all things
analog Bob Pease ran a debunking article or articles in his column.

One of the problems with fuzzy (besides the silly name, which even Lotfi
Zadeh agrees is a problem) is that it generally trades off more, and
cheaper sensors vs. controller "lack of robustness".. and in this case,
Bob's said the system is pretty much fixed.
