I had a TI-57 when I was in high school around 1979 (HPs were too expensive). A whopping 40 steps. In physics class we programmed it to display things like "7734" one number at a time while turned it upside down. > In my humble opinion, HP15C is by far the best hand held computer ever made. Here is the longer version of my tale of two calculators: https://www.astarcloseup.com/2011/08/calculator-heaven.html <https://www.astarcloseup.com/2011/08/calculator-heaven.html> I've never programmed either of them but it's nice to know that that I can. My only complaint is that none of the display modes of my newer calc are exactly right for my needs. IIRC it has to do with the zero blanking. The previous calculator was perfect. Perhaps there's open source firmware out there that can be modified. Hmm...
