The RGB2HDMI won't give me a stable MODE7 on these new PCBs. I noticed an issue in the original BOM for the board where C48 is specified as 220pF but the Service Manual gives it as 270pF. I'll pop...

Yeah, I saw that thread. Oddly, I've used the same IC, I've never had Vcc up to 6.25V (the absolute maximum is 7V over VIL) and then there's the VPP that needs to spend some time at VIH before jumping...

I think I'll just forget about that idea and get a Scart splitter. It's £50, but will split the RGB for me. That should work well.I assume you mean £5? Do you have a device for recording that takes an...

Clever stuff!I can't think of anything that good, but on a Master (but not a B/B+), could you use &FE30 to store data? I don't know how wide it is, but I suppose it must be at least 4 bits.If you...
