Thanks. I don't know if it works with TMCC, no way to test. But it does power up and work with conventional as I mentioned. It seemed to follow the QS1/PS1 conventional command control. When I got it, no movement. It was locked in neutral. I was able to get it going using conventional to change it's settings and get F-N-R function (along with start up sounds, etc.)I believe its a Digital Dynamics Equalizer added to PS1 to make it TMCC compatible. If it works it should be able to be programed and run with TMCC. Most of them failed with time though. If you have a working one you have a collectors item.
