I meant to ask about this since I have no idea what it is, I
thought it would be used for receiving over-the-air TV signals.
Are you saying they have input jacks that would work with old
computers that had TV output connections?
Indeed, those are the SAME signals! Think about it. :)
Oh, I realized he meant the modulated outputs from a
computer/console. Yeah, same signal, less propagation loss over
coax.
The RF? More propagation loss, not less.
And it's really just the composite video signal
modulated by a
carrier;
Carrier modulated by the composite video signal, actually. (sorry)
normally, if something only provides the RF out (like
the
CoCo, as folks have mentioned), you can tap the composite signal
somewhere further up the chain if you need the baseband signal.
Yes. The first time I did this was with a Timex/Sinclair 1000. That
wasn't the first mod, though...the first thing it got was a reset
button, as I was doing lots of assembler hacking on it. ;)
