mid 80s RCA Color Trak trash find (pics up)

[painkiller64]

i recently got an rca color trak jlr968wr tv out of the trash, its the first tv i have seen with a radio built in it lol. also on the back it has a coax input for a "theft alarm" (connect to ul listed class ii alarm system only it says on the sticker)

ill post a pic soon but it works pretty good for how dirty and nasty it is lol.

any thoughts about cleaning it up a bit ? and would could i use that theft alarm input for?
