[GreenKeys] Hal 6850 RTTY Terminal

[Jeffrey Golas]

Hey all, I picked one of these up recently and it needs a little love. Would anyone know the name or part # of the power switch as well as the power plug? I might have a cord that'll fit but it looks unusual for a 12v connection.

Last but not least, anyone have a sample circuit to adapt the keying output to loop? Manual says not to switch high voltage directly. I guess a simple optocoupler?
