I had gotten a Concorde 2 touchscreen cab that looks like it has everything except the touchscreen. I attempted to hook up a pc monitor to it but it doesnt appear to be the same frequency. Is anyone familiar with this cab, or able to tell me how I can find out if this indeed does work? I am looking to do this inexpensively. I will buy a touchscreen if I can find out that it works, but if not it will become my next Mame project. Any help is appreciated.
