Cheese Wedges modern art or useful

Post by Elminster » Mon Mar 30, 2015 10:31 pm

Anyone come up with novel uses of Teletext or Prestel Cheese Wedges?

Only things I can think of is:

- Use as donor box for co-pro or some other expansion
- Nail it too the wall and call it art.

Bump.

I now have received both a Prestel and Teletext cheese wedge.

Only tested the prestel one and it dials out. Not sure if any viewdata type 1200/75 BBS still about. I dont believe the couple mentioned on STH are 1200/75 although not tried.

Not sure what you could do with teletext being illegal to start broadcasting your own TV channel with teletex, apart from the Amateur radio stuff but this box would 'see' those frequency's.

So not real ideas what I can do with these apart from seel them on or gut them as donors for some other project.

It you do decide to sell them on I'd be interested in one of them, purely as a case for my matchbox copro and possibly my raspberry pi - if I ever get round to connecting it up to my beeb!

Noted. I may get rid of one or both if I cant think of anything to do with them or no one comes up with their own TV station.

But if I get rid of any you are first on the list. [Caveat unless I forget, which is always possible.]

If you have a satellite dish that can point at 19.2e you will receive plenty of German channels that still have teletext. I'm not sure how it is encoded over the air but on the SCART/RF outputs it comes out as good old fashioned teletext.

I still have no idea why the UK abandoned teletext. I used it regularly, the new slow crappy childish replacement is all but unusable unless you're the sort who sticks your tongue and use your finger to read...

Oh and you need to be able to read German and want to meet like minded hausfraus in your area

The main Norwegian channels still use teletext, or at least the ones over cable do. I wouldn't know about the digital ones.

I still don't understand why the more recent "analogue" sets couldn't just cache all the pages in the background and then provide instant viewing. Memory is cheap: it's not 1980 any more!

That would break the election campaigning monotony: "Mr Farage, does your wife still use teletext?" :lol:

So I need to move to Germany or Norway and learn to read the native language. Simple enough.

Or get one of these http://www.maplin.co.uk/p/camping-and-c ... AiY88P8HAQ

You can pick up a surprising number of satellites given enough patience to find them and point the wobbly dish at them...not included in the package are the bits of fag packet and cellotape you need to make it not wobble around in the wind...

My main satellite at home has a motorised dish and digital channels - most non uk ones have teletext still and it comes through in the video signal and can be picked up by a standard telly on a modulator or scart. I got it to watch the F1 live on German telly - never again, adverts cutting in every 5 minutes.

On a more on-topic note there are a few projects simmering away to make teletext modulators so you can add your own teletext. I looked at it a while back and it should be fairly easy to get the signal to ride on a standard composite signal - then all you need are a few back-end scripts to take xml/html from your favourite news sites and convert to mode 7 graphics...

Sounds worth a look. So possibilities for the teletext cheese then.

I think trying to use a Prestel modem would be like watching paint dry. More inclined to try and get a modern modem to run of the serial port at 19k or hack it to run off the user port at higher speed.

You been spying on me?

I finished soldering up Beebsid (that I bought 3 years ago) at 4am this morning. Then noticed that I had solder the LM7805 and LM7809 the wrong way around. look the same at that time of the morning. Swap them around tonight and make a cable.

Spying? :o Who, me :?: Well now you suspect me, best I come clean #-o

I have hacked a range of retro computers to communicate your every move via a new emerging mains transmission radio communication protocol. In addition Dalek viewing eyes have been deployed at various well hidden locations to enable multi-spectrum 4D monitoring including in the visual, infrared and UV light bands.

I know all your secrets Mr Bond, err sorry Master Elminster.

Please pay by the PayMeLotsOfMoneyNow$ service, £10 million bits by midnight tonight or I will reveal all about your secret new reverse BeebSID that plays all songs in reverse. Ooh, whoops :!: :oops: I've let the cat out of the bag.

You must still pay me or I will reveal all about something else <reaches for Betamax tape recording in large card box box marked super modern high tech>...

Must have been why K9 was hanging around at the NCC at Bletchley last weekend. Not to mention the dancing robot. Kept the kids amused anyway while I nipped off to the 80's Retro bits and had a sneaky go at Bart on the Amiga.

Sydney already first dibs on one, I guess that gives you first refusal on the second. Assuming I sell them. I will probably get rid of the prestel one, not sure on the teletext one yet. But want to play with them both a bit first just to make sure.

ah.
okey.
but it wassent me to do for the hardware it self.
i have the teletext adapter my self only no piece of cheese case #-o
and i have a cool midi interfase without a case but fits nicely in sutch a case.
thats why i asked.

mabe there ar more people who has some laying around for collecting the dust somewhere :lol:

No problem. Was just trying to work out if I could do anything useful with them. Would kick myself if got rid of them and could use them for something. Will bear all in mind if/when I get rid of.

Hi,

I've just got a Teletext cheese wedge, not really sure what I can do with it either, but . . . . . .

I have a distribution amplifier in my house that distributes TV signals around the house. (These days, it's mostly digital, but I have a few CCTV cameras that I still have on an analogue channel.)

What I was wondering was whether it would be possible to use a PC to generate some text pages, probably from Internet data, but the content is the least of the problems! The challenge would be to format the data and inject the text signal onto the one of the analogue channels that I'm using.

Does anyone here have any knowledge of this subject ?
Is the idea feasible?
If so, any thoughts on what I'd need to make it work?

Regards
Dave

Hi Dave,

Have a google for:
vbi teletext inserter

This looked possibly relevant:

and

Hi Dave

Yes, it is possible to generate conventional standard teletext pages.

Somewhere there is a small group who have done this. I don't have a link though. It may well be the people who Dave (Hoglet) linked to above.

Also if you have a motorised satellite dish and suitable satellite receiver, you should still be able to find conventional standard teletext on some of the overseas channels. As far as I know, no UK broadcaster transmits conventional standard teletext any more.

This is not due to any technical reason with the digital broadcast specifications, but because they did not want to spend money maintaining or updating the conventional standard teletext equipment.
