Anyone know what this might be for connector? TV to RCA? Something? The broken end goes to a European TV… #retrocomputing #retrocomputing #retrogames
@amszmidt The right side of the adapter looks like BNC. The left side looks like phono but based on the image of the box, it is an antenna connector. I would call this an antenna coax connector in the UK. The threaded middle is interesting but for mounting I guess.
@stug yeah, it sits on a plastic bracket. The right side is one of those normal RF / AV connectors, not really a BNC. I found one but the left hand was a F connector. Booo… the left goes into the TV, small RCA or something wonky…
@amszmidt Hmmm curious. End on photos would be helpful.
@stug the other end is just a normal TV Ariel connector .. BNC. Pardon for crap photos.
@amszmidt Thanks. That does look like a wider aperture than I would expect from anything AV I have seen.
@stug @amszmidt I would agree. We used to have those connectors for the analog VHF TV signals:

Actually I never heard either "Belling-Lee", "IEC 60169-2" or "DIN45325" being used. Every one calls them "antenna connectors". But it seems to hold up to cursory research:
@amszmidt it's the mono video connector used on BBC micros, as I recall. I don't know what it's called, but "RCA" rings bells.
@simon_brooke it’s the left hand that is giving me issues.
@amszmidt the one labelled "UHF out"? That is indeed a television signal. Hang on, let me shift computers, I'm pretty sure I can give you more information.
@amszmidt Illustration from the BBC Micro User Guide showing how to connect the computer to a television. The necessary cable is shown. The signal on the cable emulated the signal of a European television broadcast.
@amszmidt Diagram of the back panel connectors -- not particularly useful to you, except to identify them.
@simon_brooke This is the guts of some Sonix (yes .. ) TV. There is a small "RCA like" connector going to the IEC 60169-2 one .. it might even be a RCA like thing.
@simon_brooke@mastodon.scot @amszmidt@mastodon.social In the UK, convention for home computers with a UHF output was to use a male RCA 'phono' to male Belling-Lee cable to connect the female RCA on the back of the computer to the female Belling-Lee on the back of the telly.
I assume Leftpondians would use an F-connector.
(Baseband composite video was also common on RCA phono connectors. Those were usually yellow, and there would be additional connectors for the sound.)
@kim Definitely not an F-connector. This is the (female) connector I'm looking for.
@amszmidt@mastodon.social @simon_brooke@mastodon.scot That looks like a male RCA phono to me. A cheapskate one.
@kim Sounds legit, seeing it is a cheap skate tube TV. But I'm unsure about if it is really a RCA .. dimensions and all that.
@kim @simon_brooke @ksaj @stug Thanks for the help, it is a RCA to IEC 169-2 ... now I just need to find one of them to order.
@kim @simon_brooke @ksaj @stug And found something on eBay: https://www.ebay.com/itm/290732348339
Surprisingly hard to find one with a nut ..
@amszmidt @kim@fedi.social That looks very much like the plug which would fit into the UHF connector on the BBC, described by @Kim (and I'm sure they're right) as an RCA phono.
So same cable, other end.
@simon_brooke @kim@fedi.social @Kim@mastodon.scot Thanks! Now just find where to order one with threads … lulz :-). Much easier now thanks all!
@amszmidt @kim@fedi.social @Kim The curious benefits of having been very geeky about Acorn computers forty years ago!
@simon_brooke@mastodon.scot @amszmidt@mastodon.social For completeness (because it's not what the OP is asking for), that one's a female BNC.
@amszmidt It's a cable extender... the cable coming out of the wall when they're hardwired (like in apartments) is often very short, and this lets you tack on a longer one.
The part that is attached to it is a piece of a now-missing length of cable.
