[BBC-Micro] Anyone recognise this board?

Hmmm, I just had a look for my GCC one and can't find it :-(

There's a few of the external RAM/ROM boxes over at Bletchley which I suspect 
would actually benefit from going to good homes, but I believe there's only 
one controller board (the bit that lives in the beeb) in the collection and 
that would need copying to make the boxes useful...
