I found at a thrift store a small device with a delightful array of knobs and switches on the front. It appears to be made by P.C electronics, it's a model TC70-1 ATV 'Tranceiver' (spelled wrong?). it seems to have an interesting array of features, having a camera port , mic plug, and "PTL"?, on the front as well as A-V inputs and TV/Monitor outputs on the back. I originally got it for the enclosure and array of switches, but I would like to know more. I have no idea what it's intended use is, or if it could still be worth something to someone?
Thanks
Arty.
