I've ordered a couple of the extender/prototype boards Stewart mentioned here:

No luck on finding a UK UHF tuner device from folk at work yet though. I did run across my Sinclair Microvision though. Maybe dangling a UHF cable near the aerial will be enough

You can actually get edge connectors from Digikey, which can have IDC connectors pushed onto them. Might be simpler than having another board to do it.
Something like this...

I decoded all of the data area, and displayed all of the sprites and character set etc. I've uploaded it to the same thread as the ROM itself.

Would it in theory be possible to re-design the Sprite Graphics Board to be an internal add on board instead or is one forced to use the expansion port?

I'd say it could almost certainly be designed to go inside the Dragon - but it was seemingly designed the way it was (via a ribbon cable into the expansion port) to maintain compatibility with other systems.

They look great, but 3 week lead time as they don't have stock. According to the tracking I'll have the prototyping boards this Saturday, and I've ordered a modulator-composite mod board from Tynemouth Software but that will take a week or two to get here. I'll probably just get to the meetup with boxes of bits

Those would probably do. And believe it or not, they were what I originally posted. It was only when I looked at what I'd actually bought that I posted the ones with the longer legs.
I think arriving at the computer museum with a box of bits will be just fine!

Did any one manage to get some pictures of the Sprite board, If so could they be posted.
