Looking for those owning a Vision Engineering Dynascope (TS series) stereoscope. I would like to know exactly what controller I need to buy that operates my oblique attachment. Naturally I am able to manually operate it but would like to have the correct controller. The wires are cut on my oblique motor. There are a couple different models on eBay but I have no idea which one is the proper one. Seems they are always missing the cables too so I don't know if that will be an issue *IF* I find the proper controller and keypad.
