Someone has written to me pointing out a small error in the phone number
of the man who sells second-hand - I beg your pardon, second-user -
oscilloscopes. He is:

Len Cooke Enterprises,
Tel/Fax 0181 556 8221 from UK
     +44 181 556 8221 Outside UK

My correspondent adds:
Yes he is a very nice man. Not sure about the cafe.

You have to cross the bridge to get to the Waterside Cafe. It's called
"bank switching".

John Blackburn,
