Hewlett Packard improved the HP-65 in the year 1976 to compete with the Texas Instruments SR-52. The new HP-67 featured 224 merged program steps and 26 memories instead of 100 partially merged steps and 9 memories found in the HP-65.

The HP-67 still uses the Reverse Polish Notation with the [ENTER] key instead the usual [=] key.

The rivalry between calculator users of Hewlett Packard and Texas Instruments products battled a long time introducing a lot of funny benchmark programs and programming tricks before the HP-41C appeared and the race was decided.
