I have a 21 inch Sharp with a Digi Vue Card as a video input using a rs232 Elo touch controller (uses 9 pin serial).
In short its a 21" open frame touch screen monitor, with SVGA (15 pin) viedo input, Svideo, and composite inputs. and it will automaticly seek the signal. Uses 12-16v input (built in 12v regulator.
I am willing to trade for an Opus power controller and/or other stuff for my current project.
