I got a chance to DEMO the newly produced Test Pattern Generator by CraftyMech on my Electrohome G07-CBO monitor in my Pac-Man arcade cab.
The TPG outputs RGB signals to both Standard and Medium resolution monitors. It outputs both positive and negative composite sync. It allows for the separation of vertical and horizontal sync. It allows you to turn off the Red, Green, Blue colors individually. It also allows for inversion for use with Nintendo Sanyo and Sharp monitors.
