TI-58 C

Part of the 58/58 C/59 series high end LED programmable calculators offered by Texas Instruments. The 58 C might be the best of the bunch owing to its constant memory and the age of these calculators. The 58 C can retain memory and programs as long as there is any residual charge left in the batteries. This allows the calculator to store data and programs even after you turn off the calculator. The 59 had a card reader to reload programs but this is a mechanical device that generally needs repair (and the major flaw after twenty years). That is why a 58 C, even with half the memory of a 59, is probably still a better calculator to have and use on a daily basis. All are usually found with the Master module, which adds various extra programs to the function set of the calculator.
The TI's of this era have a terrible keyboard on average; i.e. 2 out of 3 are probably bad if you find them used. Best to find NOS if you wish to use any calculator for nostalgia.
On paper it would compare to an HP34C.
