That's the one.

The keys don't work very well, but I mostly thought that was because
it came from the job lot I bought from Wales - which had been stored
for years in farm outbuildings with no doors on, so everything had
rather a lot of corrosion in or on it. I was hoping that cleaning the
contacts with a fine sandpaper and applying some electrical contact
lube to them might make it work properly.

Part of the reason I never bothered was that I don't need it; some of
the Beebs I got only started up to a blank screen and a continuous
tone, so the keyboard wasn't required for anything.
