The camera has a neat B/W 1-inch CRT, and the camera only has an odd 10-pin plug which plugs into the VTR. The VTR I had could do no more than provide power into the proper pins for the camera. The input/output jacks on the side of the VTR didn't work either. I decided to rip the VTR apart to get the 10-pin socket out for the camera since it was senseless to keep such a large device that does practically nothing. In fact, I had to temporarily provide power to the VTR and camera using a computer's power supply unit. I figured out the pinouts on the 10-pin socket, and built my own compact adapter for the camera along with some fun tricks. Below is a picture of the adapter I built.
Below is a diagram of the pinouts for the 10-pin socket which the camera plugs into.

I pulled out jacks from a TV board and used them for my inputs and outputs on the adapter. I also pulled out the video/audio modulator from the VTR in case I wanted to modulate the video and audio from the camera or inputs into RF. Below is a combination schematic and block diagram of my circuit.

I used a switch to select whether I wanted the inputs or the outputs (camera video/audio) to be modulated into RF. The modulator had a channel selector, which was channel 3 or 4.
The audio input is only for the modulator, the camera cannot play audio. My camera has a switch on it for selecting the viewfinder to display video from the camera or VTR. The input video will be displayed on the camera's viewfinder when it is set on VTR, however the modulator should be set to modulate the outputs (no connections with the inputs) to prevent interference. Video from a VCR (the VCR can separate the video and audio from RF) was fed into the viewfinder. I also fed video from a Nintendo game into the viewfinder. Below are examples of video I fed into the camera's one-inch viewfinder screen.

The output video from the camera can be viewed on the viewfinder when the selector switch is set to camera instead of VTR. Below is a example of the camera in operation.
