The Rainbow outputs a normal RS170-like composite video signal with the same timings (so 15-odd kHz horizontal, 60Hz vertical). There is a setup option for 50Hz vertical I think, if so it's going to be close to European analogue TV rates. This composite signal is the monochrome output. If you have a colour video board, it is used as the green signal (which is thus SoG) and there are separate red and blue signals. Obviously all at the same rate. -tony
