The doc project has the datasheets to download, in fact it has most of the
important bbc related chip datasheets.

These are not OCR'ed though and some of them are on the large side. Mind you
depends on what you used to. If you use MS software then you will consider
them quite small files, if you are used to word processing files from the
BBC, then I would ask a friend to download them :-)
