X-Y Monitor Tester
At one time I was considering buying some spare X-Y display monitors for some
of my video games. I needed an easy way to determine if the monitors were
basically functional, so Rich and I built this tester using a PIC16C54 and
a quad 8-bit D/A converter. It displays several simple geometric patterns,
stepping through the patterns when a button is pressed. We didn't build any
vector circuitry per se, so it draws lines by plotting a series of intermediate
points.
