Chotken-HP49-PE-CE review program
I have a HP49-Chotken-PE-CE review program calculator. The profession exam program is pre-programmed in the HP49 calculator and seems cannot be unloaded even when batteries were removed. I do not know how was that done and what part of memory it uses in the HP49. Can anybody out there explain ! Thank You.
