And going back every second Saturday to renew the same book, again & again...

Some comments here are like I wrote them. I got an old ZX Spectrum clone from my aunt when I was a kid. Badly obsolete at the time so I did not tell my classmates who already were playing Diablo and NFS on their 486s. I remember scavenging library for these colorful books all the time. They really fascinated me. I think they got one thing right; kick-start the imagination and make kids learn by playing around.
I had the same thought; I remember the covers and titles of several on that page. I never owned any, but I borrowed several from the local Library and fought with my 48k Spectrum to get them to run as a child.
