that fuller with the extension, and, yes, rampack is mine

if you'd like the dimensions of the extender board, give me a few days to dig it out (part of my 'round to it' pile) and measure things

That would be great thanks!

I use thin double sided tape carefully cut to size for fixing partly loose labels.

Thanks Mark, I think I should retain the original sticker.

I've started to vector trace the extension PCB photo now in Illustrator. I'm not able to see the connector under the 16K expansion that's plugged into it in the photo but once I have the accurate measurements I can try a first test print out to see how well everything lines up inside the case.

I'm eventually getting back onto the Fuller FD42 build. I was considering making the missing extension board with some large stripboard sections cut to the correct sizes and epoxied together. I don't have the correct dimensions of the original board however. I have an old defunkt interface that I can take the connector for the connection to Zeddy board but I'm unsure how to progress with the two edge connectors, one is vertically mounted for the internal interface and the other one is the horizontal edge connector for the back of the Fuller case. Is there somewhere I can source a suitable edge connector?

@martin: he is searching for the opposite end, the PCB that goes into those connectors you linked.
In theory, there is no difference between theory and practice. But, in practice, there is.

That’s just making a pcb and order it from Oshpark or China.

If you ask PokeMon, he may be able to supply just the PCB from his extender (see
here or search these forums). PokeMon is a member here.
I don't know how suitable it would be for the purpose that you want it for...
