d'oh! I knew there was one I was forgetting! :)

I wonder why the IEEE488 was first? Presumably Acorn had some high-profile 
clients that needed it - possibly people still using System hardware who Acorn 
wanted to move over to the beeb.

Andy Ray of Intelligent Interfaces (who made the boards) is lurking on the 
c.s.a.h newsgroup and will probably remember a release date - all he says in 
his last post about the boxes was that it was the early '80s .

Wonder about Prestel though? I can't remember if the board in that is an Acorn 
design or an off-the-shelf modem board (as other manufacturers of the time 
often used). If the latter then I imagine the Prestel adapter was a really 
easy product to bring to market, so could well have beaten the others...
