You could think of the TTL signal as a three line parallel digital signal but that's not how the TV/monitor sees it as it's treated as three sets of analogue signals. These are then put through an A-to-D converter. Scan line synchronisation could be an analogue circuit like old monitors or it could ...

I think I got that pamphlet before I got the QL. What I noticed was that the QL printed on the front (when folded out) was life size, which nicely showed how big the QL was. I think I still have two copies around. I don't know if a similar pamphlet was used in the UK, but this one was written for t...

If you try and OSSC, which does cost a lot more but is worth it, it's better than you'd get with a TTL RGB display. That would be a magical transformation indeed. Even higher fidelity than the original. That's easy, CRTs smear sideways due to the speed at which the beam can switch on and off and ar...

I have tried OSSC. The picture I get with a cheap Chinese scaler on a cheap Chinese PC is way better than from OSSC together with an expensive NEC Multisync - So your mileage may vary. It is, however, a bit of a lucky game with the Chinese scalers whether you get them to work properly with your spe...

Those cheap scalers are OK, though it depends upon the TV as to whether they will display the extra characters, most don't. As for scalers being "fuzzy", well the cheap ones (which are really designed for video) do rubbish interpolation and also erroneously sharpen the image, so they don't...

If you want HD then the 1772 can be overclocked to 16MHz to do this, as used in the Atari TT030.

To be specific, would it be possible to replace the RF out with a standard VGA port? Obviously keeping the QL standard 512x256 @ 4 (or 8) colors. You'd have to create a scan doubler. Given that VGA is getting rare now you might as well go the whole hog and create an HDMI output. You could probably ...

Lithium coin cells do burst and leak but I've only ever seen this once and it's extremely rare. This is totally unlike the NiMH and NiCd rechargables or the half-AA lithium batteries which seem to eat through their casings very quickly.

Coin cells are by far the best solution.

The TT's video sub-system is very different from the MSTE's. Could the system be trying to switch to TT-High resolution, which is not VGA compatible? Have you tried starting SMSQ/E when running in ST-High resolution? I must admit that I tried running the latest SMSQ/E on my TT and the display didn't...

PS. Ignore the Perl script. If there are no instructions, it's unlikely the code could be read and understood, even by the authour! Perl is a 'WORN' language. Write Once Read Never! :D Bah! That depends upon the programmer. Some write Perl which looks like line noise, others as a clear, structured ...
