Yup its a Sanyo probably with a Sylvania jug. The input is probably
whats called TTL (IIRC) for early computers. Dont remember any
VTR's etc that had RGB. All I have seen were standard composite
& audio. Have seen this connector for computers on a few high end
sets. May take either ??? Very surprised it showed up on a Sears.
