Subject: BBC B issue differences?

Hi,

is there an easy answer to what the differences are between the different BBC B
issue numbers? Just going through my collection and I seem to have issue 3, 4
and 7 machines - with 7 being far more common. I don't recall ever seeing 1 / 2
/ 5 / 6's. (possibly 1 and 2 were model A machines? Certainly my ICL-built
early machines are still issue 3's)

I believe the B schematic I have is for an issue 7 machine - are the others
floating around the 'net somewhere (if sufficiently different) or could be made
available?

cheers

Jules
