Couple weeks back I scored this beauty - Sakata SG-2000 Monochrome Character Display. I couldn't find a manual for it, but internet resources suggest that it's compatible with the Apple II family, and hence should require the same composite input as the Apple Monitor II.

I want to check if the poor thing is even alive and operational, and the only device in my place that can theoretically output a composite signal is a Pi Zero 2W. I'll need to solder half a cable to some test pads to get it out
