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).

TI-58C: The TI-58C changed the architecture of the original TI-58 slightly. Removing the old-fashioned TMC0598 RAM’s found in both the TI-58 and TI-59 it introduced a low-power C-MOS RAM connected permanently to the power supply.

This programmable scientific calculator, introduced in 1977, is more powerful than the TI 57 and less so than the TI 59, which were introduced at the same time. It has a black plastic case and an array of forty-five rectangular plastic keys, most of which can assume a dual function.

The Texas Instruments TI-58C Programmable is a programmable calculator with 11 digits precision and algebraic logic. It has 45 keys, and an LED (light-emitting diode) display typical of calculators of this era. The power source is 3xAA battery pack. The calculator was manufactured in Holland; USA.

The TI-58C was introduced in 1979 - it was a TI-58 with continuous memory and some minor internal software improvements. The TI-88 was supposed to succeed the TI-59. It was introduced in the summer 1982: alphanumeric display, 416 registers (3 kilobytes) and advanced symbolic language attracted many TI-59 owners, but the calculator was withdrawn ...
