They have all sorts of 'blackbox' data acquisition products. I used
their rs-485 stuff to connect 4 O2 sensors, 4 EGT probes 12 pressure
sensors and a crank angle sensor to a Palm TX when I was debugging my
Megasquirt setup on a 1946 CJ2a with a supercharged L134 flathead.
Their stuff just works! My initial runs were with Quartus Forth on
the Palm TX, but I moved up to a VIA mini ITX running Gforth under
Slackware when I needed more bandwidth. I like their serial DA stuff
since it's easy to write the code, but I'm sure their USB solutions
would work just as well.
