Two of these, the HP-33C and the HP-38C, were exactly the same as earlier models except for the addition of Continuous Memory. The other three, the HP-34C, the HP-37E and the HP-41C, each deserve a separate article. Indeed, the HP-34C deserves a whole book, and the HP-41C deserves far more...."

Craig A. Finseth concurs on the first of July, 1979 for all those 5 models.
