However, from memory, the board intercepted the signals to/from the video IC socket, and then the Atom's displaced video IC (umm, a 6847 I think) plugged into the colour board itself. I think that the 6847 chip was colour-ready anyway; it's just that the standard Atom doesn't include the necessary circuitry to make use of it (I think the floating point ROM actually contains the code to make use of the board). I also have a funny feeling that the colour board didn't provide component RGB - it'd only allow colour via the modulator and displayed on a TV. All the info - including schematics / parts list / theory of operation - is in the manual for the board; every so often I toy with the idea of building one, but then decide that it's a lot of effort [1] for not much gain (after all, it's not like there's a wealth of software out there which uses the board, so I'd be limited to whatever I decided to write myself) [1] Relatively speaking. The circuit's not complex, although I have a feeling that some of the listed parts may be hard to find these days. I'll dig out the manual tomorrow (I got back to the UK earlier today) if I get the chance and flick through it for useful info... (amazingly I know which shelf that one's on, but I'm about ready to fall over here :-) Heh, I don't think I've ever heard of the latter one... true :) Indeed. It's a shame, but then it's bad design on Acorn's part as it was pretty obvious that relying on a sticky label being present wasn't particularly foolproof! cheers Jules
