You do realise that BNC connectors were used for RF
and video
Well, it stands to reason, I suppose.
applications long before there was any form of
ethernet, I
take it. The
video ones are likely to be '75 Ohm' characterisic impedance,
so you'd
have to get the right plugs to fit them. 50 Ohm plugs will
fit, but the
larger centre pin will spread out the contacts on the socket.
And anyway
you'll have an impedance mismatch. I doubt you'd notice the slight
ringing from that on the screen, but it never hurts to do
things right.
I have a 50-75 ohm converter, I believe. I'll need to dig it up.
it's separate outputs for the standard (40 column)
video from the
motherboard and for video from an 80 column expansion card.
Hadn't thought of that.
