I got this today attached (badly, with much blu-tack) to a zeddy.
It is a very nice keyboard to use!

Given the height of the pins any idea how this was supposed to be attached? Just a few layer of thick double sided sticky tape?

Nice ! what is the purpose of the red key ? The tracks do not seem connected to anything on the back ? Are they ?

Not sure about the red key!
Here is a close up.

I think the red key is unallocated. It looks like it’s connected to the unused pads where the eight way ribbon cable connects to the board. Hence it’s not part of the keyboard matrix.
It could be used as a reset button if wanted (although given its position, I’m not keen on that idea).

I still have this keyboard somewhere and If I recall correctly it was attached with the thick double sided "sticky foam" similar to what Karl uses to attach the top layer of his "Clicky" keyboards.

I got one of my ZX 81's working today using this keyboard,
- Iss 1 with vLA81 and Kempston keyboard
The red key doesn't seem to do anything, so far
I thought that it looked like the return/enter key.

Um, surely you mean’New Line’ not return/enter….
About the red key, did you read my earlier post?

I've never had a working Zeddy before.

Seems too ostentatious for something that's got no function
