Yes, modules with laser trimmed resonators and thermal compensation, quite expensive, but wow, so good. Replacing the Beeb crystal circuitry is quite straightforward, just remove X1 and inject the signal onto the inverter IC43 pin#1 as the Cox genlock boards do. I decided to go the whole hog and replace the shimmery 6MHz glitch clock with my own viewtopic.php?t=18521 and I've got to say MODE7 looks splendid on analogue RGB, even better than the RGB2HDMI as the character rounding/half pixel function works properly and the screen doesn't wobble on a CRT.ive always used these oscilator modules [ https://uk.rs-online.com/web/p/crystal- ... rs/7675336 ] in project and im guessing it could be used to replace the oscilator circuit in the beeb too
