I am a psychotherapist and am designing several different research projects in which I will be collecting physiological measures from human subjects while displaying graphic images to them (digitized photographs mostly). I have the data acquisition part working using an AREXX program to collect and sample the physiological measures through the serial port. I am now trying to figure out a way to synchronize and display the graphic images on one monitor while being able to watch the AREXX data acquisition on another monitor. I would prefer to do this with one computer, if there is hardware available to do so. If necessary, I could work with two computers, but would need to be able to control the computer that does graphical display from the computer that does data acquisition. Does anyone know of a way to output two different displays to two monitors from the same computer? If not, what would it take (besides a serial expansion) to drive a second computer to display graphics (controlled and synchronized by the first computer)? I own an Amiga 2000 and several 500's, but could obtain whatever hardware is necessary. – via Whap!
