Just today I got one of these from an eBay auction, including the original cable in a sealed plastic bag. The ROBOLAB software wasn't included, however, so I imagine that I'll need a driver of some kind to use it. Does anyone have a driver? (This (...)

I've taken some more detailed pictures of the circuit and the reverse side.

I'd like to try to convert the output of the voltage on a 9750 from 4V to 12V (to control 12V trains :).
