HP-41C could be called a small revolution in the pocket. Following the path of
programmable calculators like the HP-67 or TI-59
it overcame their limitations of the stupid men-machine interface possible with
a numerical keypad and a 7-segment display. The HP-41C added alphanumeric
capabilities to both the display and keyboard using 14-segments and an
ALPHA-key. In addition the memory capacity was enhanced and uses non-volatile
integrated circuits (RAM) like the TI-58C.
A total of 4 slots allowed further expansion of either RAM capacity,
pre-programmed ROM-modules or peripheral devices like a card reader or printer

similar calculator – unfortunately it never appeared in the market place. It
took some time before Texas Instruments took the leadership again with the first
Graphics calculator TI-81 in
