@Lobst we should get our CRT up and running... It's only mono audio though and we'll need to find a BNC to RCA adapter for it (it's a model meant to be a security monitor, so it would normally be hooked up to a security system, which normally use 75 Ω BNC connectors on RG-11, though they still use the same composite video signal)
oops i started rambling
