Or both so I can double-check.
If you have time I wouldn't complain. The one thing print a template wont tell me is where the side button hole is, so that would definitely be useful.
Thanks.

If you have any, I recommend using "lip and spur" drill bits (also called a brad point bit or dowelling bit), as these give a cleaner cut. Normall HSS drill bits just seem to melt the plastic leaving a crater rather than a clean hole!
I just know them as wood drill bits, yes I do have some.
Ah yes, a step drill bit would be similar to increasing the hole size gradually. i've never actually bought any of those.
Yes, it should be possible to make this work with a Dragon.
I agree, the Y amplifier is different, and the Y output includes the colour subcarrier from the LM1889.
I was wondering if this would be possible (and planning to try myself later this week).
Yes
1. Lift pin 14 of both U1 and U2 to isolate the Vsync and Sync inputs and then feed V and H sync from the Atom 10 way connector directly to the TTL header.
I just got the RGB/YUV interface board working with the dragon:
It ended up working in a slightly different way than I envisaged with the 6847 sources (I had to make one minor track cut and link and use different input signals) but after that change it works really well with everything I've tried so far.
That's great.

I was following the instructions blindly and missed that Fortunately, there's just enough space to be able to solder with the IC socket fitted, but it was a bit fiddly.
Yes, I've done the same.chrisn wrote: ↑Sat Mar 07, 2020 11:22 pm I've also made up the noise killer board, but Farnell sent me a wrong IC, so I haven't been able to finish this yet. Trying to fit the board to the Atom, I found that there wasn't much clearance above the 6847, so I put in extra IC sockets to raise the board up a bit.
