The book that got me started 45
Interesting... the book must have been written by someone with a lot of exposure to the IBM System-360 family of systems, because almost all of the illustrations, especially in the '71 edition, are of IBM hardware.
I notice too, that the chapter on digital communications is called "Teleprocessing", which was actually the IBM term. In fact, I'm pretty sure that IBM registered that word as a trademark. However, I also recall that a lot of IBMer's would use the word generically (often abbreviating it "TP"), so it could well be that IBM may have lost trademark protection for that reason. At least this book seems to have slipped under the legal radar.

I notice that the illustration in the '71 book with pictures of keypunches and verifiers (in the chapter "Does a computer make mistakes?") was replaced with a roomful of 3270 display terminals. However the accompanying text still tells of using keypunches and verifiers to ensure that the data is entered correctly. I've never seen something equivalent to "verifier" operation done via display terminals. ...and no doubt there are a great many more keying errors getting into systems, too! Oh, for the paranoia of yesteryear!
