Hi Ian,

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.
