There's more to it in the article (I've left the calibration run and backtracking option out of the HELP part, but the program listing is complete and includes them).

I never had a HP-55 so it was surprising that this program gave me quite a sense of nostalgia. It started when I saw keycode 81 as "/". The later woodstock calculators don't have a row 8 ... with only one exception. The one I used most is that exception. STO and RCL here are familiar keycodes and, whilst not in this program, 84 always causes me to think of R/S.
