     I have ordered this ARM board to build a EFI system around, written in ARM
     compiled
     BASIC.

     It should be here in a few days DHL.

     We shall see how it goes.

     I should have something running in about a week.

   Paul,

   Could you give us the info on this board so we could consider buying one
   also.

   I am thinking of some developments to our robotics products.

   Here is the ARM board. It has infinite expansion potential.

   I am working on two systems. I am working on a parallel approach as well with
   a real simple and old CPU (8051 not a C8051) controlling mostly hardware.

   If you are interested in the simple system let me know. It will very limited but it
   is quicker to build and program I hope. I will be testing some of the hardware in a
   few days. I'll know then if it is going to work.

 Hey Paul,

 I was thinking about leaning on the way home tonight.  How about this.

 Put a rheostat/pot in the cockpit that adjusts a simple voltage divider
 so that the output can be varied across some arbitrary range.

 Connect said output to the A side of an A/D.

 Read the knob position from the D side of the A/D and use that as the
 multiplier for the pulse width generator.

 You wouldn't even have to use a high fidelity A/D.  Eight bits would be
 overkill for our purposes.  Set the knob in the center and use that as
 the base.  Higher is richer, lower is leaner.

 That is what I planned.

They say that great minds think alike.  Do you have any idea where I can
find one? ;-)
