But that's the rub John. He has a calculator that converts decimal to
binary for him, and he knows how to work it, but he can't grasp that the
number showing on the screen is the positions the switches should be in.
It's is something that is getting to him, that doesn't want, or can't, see
the translation. Weird ! :-))

I use binary and hex every day but *STILL* have problems with PC manuals which
show black and white pictures of DIL switches. The biggest problem (having
worked out which end is which) is deducing which part of the drawing actually
depicts the switch 'lever' (black or white).

e.g. something like
--------
| ####|
--------

now is the switch set to the left or the right?
