A page of the Fun In Less Than 4K chapter of the above book, with Program listing 9-5 called "Teeth Wisdom". The text is lines 110-170 of a BASIC program, printing out a header with a box made of asterisks with the text "TEETH WISDOM" at the centre. The rest of the program is cut off.

@permacomputer @mdhughes #TeethWisdom sounds like a #DoomTree album name.
