I am not sure of the whether the books are being made available copyright free at the site. Therefore, I am not advising anyone to do download them, but for those who started learning about Computers in the 1980s the covers may bring back a few memories.
Apart from that though, the style of the books is interesting and I feel relevant to needs now (even if the languages used may not be as relevant). The reader is taken, step by step, through concepts by cute robots - I am starting to wonder as I writing this whether my own style of teaching computing has unconsciously being inspired by these books.
All views are those of the author and should not be seen as the views of any organisation the author is associated with.
