I doubt that all would have been readable on the screen, but think of the wow factor in printing well formatted resume with what you carried into the interview in your briefcase......... in 1984.

You could always print lowercase on the 82143A, using lowercase mode (flag 13) if nothing else, but my most recent memories of using a 41 were with a 41CX, where you could put lowercase letters in the alpha register using XTOA (or synthetics, of course). Which you would also have been able to do with a 41C or 41CV with an Extended Functions module. The calculator would only show lowercase a-e on the display, f-z being rendered as all-segments-on blobs, but they would all print correctly.
