I feel a strange sense of loss at learning that these exist. I cherished the Usborne books I did have, and I had to mainly teach myself Basic with LIST commands and such, because I didn't have any friends or comprehensive books to teach me, nor was I permitted to dial long distance numbers to reach a BBS. I would have loved these as a child.
