Another thing that somebody was asking was: where do you get a
second-hand oscilloscope?

The answer, if you live in UK (South) could be:

Len Cooke Enterprises,
Tel/Fax. 018 556 8221

Mr Cooke is located in East London and is a very nice man. He has a
small warehouse stuffed full of testgear of all kinds. Everything is
tested and in working order.

A used double-beam 20MHz scope can be bought for around UKP 100 or less.
This is a suitable spec for PIC-users. A 100MHz scope, if you need it,
would cost about UKP 250 or more. Scope-probes are not included; you
will need a couple of switchable X1/X10 probes, which you should buy
NEW.

If you feel you need a Handbook, ask Mr Cooke and if it exists he will
send it. But don't expect postal charges to be cheap, if you want it to
ARRIVE in working order.

I collected one from his warehouse. Afterwards, I recommend driving to
Coppermill Lane, park just before the very low bridge, walk under the
bridge to the canal, and go to the Waterside Cafe for a really cheap
lunch; for example, egg sausage and chips and a mug of tea, less than
UKP 2. Then go back to your car to find that your oscilloscope HAS NOT
been stolen. Just like the old days...
