If it has the red, yellow, white connectors, it's an RGB monitor. If you have any computers that can use it, hang on to it. I remember back in the 80's you had a choice of using one of those or a television for your Atari's, Commodores, etc. Everyone I knew who had an Atari, actually used the Commodore RGB monitors. it was the only thing we would actually give Commodore any credit for because it was the most readily available color monitor you could buy and was usually a bit cheaper than competing color monitors. A lot of people had monochrome amber monitors from Amdek, but it wasn't the same as a real color monitor. If you have a VCR with the same outputs, you can also use it as a television. I used to use a data switch with mine for use as a television or computer monitor.
