But
The Tube hardware wasn't that well documented either. It was based round
a ULA which wasn't covered in the Advanced User Guide...
Well, the ULA wasn't in the Beeb but in the add-on, so that's not so
surprising. Most of the other addons aren't well documented (or even
mentioned) in the AUG. Don't forget that, although the authors had a lot
of moral support from Acorn, they had no official backing.
