tmart, your set looks to only have a rod antenna for RF reception which would match with it's VHF only tuner...no screw terminals. The big UHF connector (as us old guys used to call it) is only for a 75ohm signal from a video source as it has a termination switch which is a video only function. And I see no audio-in connectors. (Correction...there is a 1/8 mini above that is the audio in that I did not spot). You can use any known adaptor for the UHF as long as it is a video source. No RF signals need apply. How your set sees fuzzy pics feeding RF to the UHF is unknown to me unless there is some interaction between the UHF and the rod. I suspect your RF modulator to the UHF connector is spraying stray RF inside the set that the rod sees but not very well.
The "tv out" connector is whatever is on the screen again in the video format.
The other connector is an 8-pin EIAJ connector widely used by Sony in the late 70's and early 80's on mostly 3/4" decks and some others later for ease of connecting decks and monitors together with full video and audio. They usually came in 6' lengths.
The 8-pin connector pinout is below courtesy of the always helpful Labguy.
