HP15C LE vs. HP15C
Now the moment has come, when I put my HP15C LE finally into my collections display cabinet, since he only shows up Pr Error, no way. If I understood previous discussions to this "feature" correctly, it's due to an error by design, maybe correctable with a new firmware.
I bought this unit last October from thecalculatorstore, so its age is only about nine months ![]() Now I'm using again my good old HP15C of 1987 U.S.A. (maybe on its first batteries?) 100 times slower, but nevertheless working like a charm ![]() |
