The H-board you speak about is an H-Bridge (named so because the schematic
resembles an H formed from transistors and the motor as the horizontal bar). I
may work on some sort of interface to take the pulses from the link port into
a constant voltage. I won't have to if I can make the H-bridge trigger on a
pulse and stay triggered just slightly till it get's no pulses. It won't be
dificult. The H-Bridge is a good circuit (I use it exclusively in my small
robots!). Chances are, I'll just recreate the board from my 2 motor walker and
throw it into the rumble pack. I think I need to make it smaller though.

Actualy It just barely fits. I only need about 1/16 inch trimmed off!
