Motor Drivers and Shields for Panda II

GHI used to make a motor driver shield for the Panda II, and I believe there was also a shield class in the hardware namespace, but am not sure about that. I recognize things have moved on and the shield and drivers aren’t available anymore, but I got my 13 year old twins interested in programming a Panda to do some robotics before checking out what is currently available. Is there a link to some old code or driver details that might save them some time & mistakes in writing a new c# driver?

They younglings haves already purchased a SainSmart L293D Motor Drive Shield, so they’re looking to translate the Arduino Duemilanove Mega UNO R3 AVR ATMEL driver code to c# and use the Panda II rather than start over with the Arduino. We have the borad schematic and understand which digital pins are needed and what they’ll control, but it would help to see what was done for the Fez before. Any suggestions would be appreciated.
