I think this was the first video camera that I bought. I got it as something to fiddle with while I was studying electronics (which included television and video). It's not a particularly brilliant camera from the 1970s, although it was surprisingly sensitive for filming in low light, for its age. Its scan linearity is poor, the scanning circuitry screams extremely loudly at 15 kHz. It's quite heavy, for such a small camera, and happens to be quite dirty (it's ex-school equipment). It runs from 12 Volts DC, and requires an external sync generator that's generally provided from a half-inch, open reel, portable video recorder (which I don't have). This one's been slightly modified so the cable comes out the back, rather than the bottom, so I could get it to sit on the tripod that I used to use with it.
