RCA CKC-021 - believe I had one for a while in the mid 1980s. As I recall it was paired with a portable (battery powered) RCA VTR (VKP-900) that had, would you believe, a stereo linear track (but no Hi-Fi audio). It included a docking station for the VTR that provide a tuner section and battery charger. The VTR powered the camera - no need for the separate power supply unit. The setup worked OK, but the image it produced was I thought rather soft, even for VHS of that time (in retrospect it might have been a poorly adjusted backfocus on the camera). The camera and VCR kit sold new for about $1500 in 1985.
As noted in earlier posts, the camera was 4x3 aspect ratio (essentially a 486i image), as was all NTSC TV back then. The easiest way to get a 16x9 image out of it would be to crop about 60 lines each from the top and bottom of the image and then scale that to fill a wide screen. Not a very satisfying picture. You could attached an anamorphic adapter to the lens, if you could find one that will mount on the camera, but they cost real money.

Given how cheap basic HD camcorders are today, or even used Mini-DV camcorders, hardly worth what it would cost in time, effort, and additional gear to make this relic usable, except as a labor of love for old gear. More modern gear does much better in poor light, is much more portable as well, and stores in a digital format for easy transfer to a computer.
If you really want to digitize the video output from the camera, any SD analog video capture card/device that works with your computer and software will probably work. Other threads discuss capture cards in depth. But test the output from the camera first (maybe connect the camera to a friends TV set - it is portable) to be sure you actually have a video output signal worth capturing.
