National MM5766 dynamic key sequence programmer can be added to MM5758 scientific calculator chip to provide learn-mode programmability. Cirouit memorizes any combination of key entries up to 102 characters while in load mode, then automatically plays back programmed sequence as often as desired in run mode. Halt key programs variable data entry points at which control is temporarily returned to operator in run mode.- MOS/LSl Databook, National Semiconductor, Santa Clara, CA, 1977, p 8-76-8-79.
