This is an AWR FRGEN Universal Drive Box. It was built to run Vixen MT-1 (8-pin) motors on a Great Polaris mount. It was part of a project that was never completed and I have since sold the GP.
The FRGEN will need to be tweaked (via serial port) for best performance. I will do my best to answer questions and also recommend the AWR web site.
Any reasonable offer considered.
