I came here to ask if anyone could remember this weird handlettered book on BASIC which illustrated all kinds of concepts including linked lists using arrays of boxes and arrows. I believe this must have been it unless there’s another book that was like this. I vividly remember as a kid reading all these different books about computers and programming. I found that I had to read a bunch of books in order to find the right mix of explanations that gelled in my mind. Instead of reading one or two books on BASIC and getting frustrated, I probably read a dozen. This one really appealed to my visual brain.
