content: This programmable scientific calculator, introduced in 1979, is a successor to the TI Programmable 58. Unlike its predecessor, it boasts constant memory (that is to say, programs and numbers could be retained when the calculator was turned off). It has a black plastic case and an array of forty-five rectangular plastic keys, most of which can assume a dual function. The calculator could be operated manually by pressing keys. It could run a variety of preprogrammed routines from a module inserted in a compartment in the back of the case. Programs could also be entered using a set of keys and stored in one of ten locations (denoted by the letters A through E and A’ through E’).

Behind the keyboard is a space that would hold a paper label describing a program on a module (the module itself is stored in the back of the calculator). Behind this is a ten-digit display that may also show eight digits and a two-digit positive or negative exponent. An on/off key is at the back and a jack for a power supply on the right side.
