The '''TI-68''' was a scientific pocket/desktop [[calculator]] produced by [[Texas Instruments]].<ref name="dcm03" /> It was introduced in 1989 and was modified in 1991 to produce a less expensive and possibly more durable version. The adjacent picture is the later version. It was discontinued in 1997.

A wealth of features made it a versatile calculator. Named [[Variable (programming)|variables]], and [[interactivity|interactive]] [[formula]]s of up to 79 keystrokes, could be stored, subject to a total [[computer memory|memory]] usage of 440 [[byte]]s. Some features included a [[simultaneous equations]] solver, a [[polynomial]] root finder, two-variable [[statistics]], [[complex number]]s, and a recall feature, which would display the last equation entered and its answer. It had several features useful to computer [[programmer]]s, such as [[radix]] modes and conversions and [[bit array|bitset]] operators. It had an [[alphanumeric keyboard]] and [[liquid crystal display|display]].

It was also offered by [[Radio Shack]] as model EC-4044, but in a different color scheme.
