I found an old Telerate green monitor at a thrift store and figured I could run my computer output through an HDMI -> AV converter with no problem, or a Raspberry Pi composite output signal. Turns out that isn't the case. The monitor will display the HDMI/AV converters test screen, but not my actual computer signal. As for the Raspberry Pi composite signal, won't display anything. I connected a camcorder via the camcorders 3.5mm AV output, and that did display video brilliantly. Just connected a cheap DVD player from the VIDEO OUT port, that worked as well.
Dying to use this thing as a terminal, what needs to be set in the Raspberry Pi config to make the composite output the same as that of a camcorder or DVD player, or is it impossible using a Raspberry Pi. In that case, is there another microcomputer that will display to the screen?
