About 20 years ago, I had a childrens book about computers. Japanese-style (comics, with the style of drawing a La Doraemon). In two volumes. Which is very popular was covered in a principles of computer architecture, Boolean logic, protocols, encryption, and other. She was in two volumes (as far as I remember). Printed in four or five colours max (even without the gradients :)
Recently I remembered but, of course, neither the author nor the names of course, I also don't remember.
Attention — a question!
Anyone that might remember? It would be very interesting to find...
