Re: Teletext Adapters

Hi, I see Teletext Adapters being sold on eBay, is there a use for Teletext these days. As I thought the signal had been switched off. All the teletext services have indeed shut down in the UK (though are still going strong elsewhere). There is however a growing enthusiast community and there are w...

Re: Teletext Adapter Service Manual

Thanks for that, unfortunately the only ATS 3.0 I could find was for the Morley or Acorn Advanced Teletext Adapter and both of those use the User Port. As I say, the one that ships with BeebEm is the correct ROM for the cheese wedge. As far as I'm aware the "Teletext System" and "Advanced Teletext ...

Re: Teletext Adapter Service Manual

Yup, I did exactly that, I burnt an ATS2.5 ROM (I found a pile of old BBC ROMS, Wordwise+ etc. that I sliced the sticker off and cleaned the quartz window and rejuvenated the pins with a PCB pen and leg straightener tool) and it works perfectly! :D There's an ATS 3.0 which the one beebem ships.

Re: Teletext Adapter Service Manual

I bought some New Old Stock modulators from Germany to build my "Teletext Insertomatic 4000". They're ALPS MDLP3W104A which are "modern" electronically tuned units which I hooked up to the Raspberry Pi I²C pins via a mosfet level shifter. They need a 30 volt tuning supply which I generate with a sli...

I had a similar issue with my TTX2000S for the Speccy where the tuning wouldn't stay locked on. That turned out to be a bad ceramic cap near the tuner. I only found it by probing...

Re: Acorn Discord group?

The best thing to do is just start one and spam the links and a little explainer everywhere interested people already congregate. It'll either take off or it won't.

Re: beeben save preferences

There's a DiscIms setting in the preferences.cfg but it seems like it gets ignored and reset to DiscIms. This seems like a bug to me.

Edit: found it, there's a single character typo in the source. I've raised an issue for it on github

Re: beeben save preferences

When you installed BeebEm did you create your user settings directory in a protected location (like under C:\Program Files etc)? This should be somewhere where you can modify files without elevation, usually your own user profile (i.e. below C:\users\<foo>\) You can change the user directory associa...

I'm figuring that exactly nobody has a teletext adapter plugged in any more, so this will be safe even if run on real hardware.
