Aha, thanks. I think that whatever equipment I might ever want to connect
the machine to will be using an F connector, so straight-through will do
the job. I did find a lead at a shop yesterday though with DIN connectors
at the end (original purpose unknown), so I can butcher that and make
myself up a composite lead.
Oddly, I never saw a TV switch box in the UK back in the day - everyone I
knew with any kind of machine that used a TV for a display simply unplugged
the regular antenna and plugged the computer in when they wanted to use it.
1) When hooking this up to a TV via the RF input
- is there any "magic"
involved, or will a suitable braided co-ax TV cable with a phono connector
added at the Atari end do? I know it "works" because I lashed one up
Maybe... The modulator output is nominally 75 ohm, and should be linked to
such a piece of coax. European TVs have a 75 ohm aerial input, often on what
we call a 'Belling-Lee coax socket', so it's just a cable. US TVs, I am told,
may have
either a 75 ohm coax input, often on an F connector, or a 300 ohm balanced input
(for parallel twin feeder cable) on a pair of screw terminals. For the former, just
connect it up. For the latter you may need a matching transformer... (BALanced to UNbalanced converter). I am pretty sure
you can buy these, but
it must be possible to wind one if you can get a suitable core
I do see ones for old video game consoles every once in a while, I've just
never picked one up as I have monitors (CBM, Apple etc.) that will work
with the other machines I have over here. Maybe I'll grab one at some
point, just in case I ever need it for some reason.
