|Model:||TI 58 C|
|Type:||Programmable scientific calculator|
The TI 58, TI 58 C
and the TI 59 are
programmable calculators that can be extended using Solid State Software
The TI 58 C has non volatile memory (constant memory).
This series of programmable calculators (TI SR-52, TI SR-56, TI 57, TI 58, TI 58 C, TI 59) really set the tone of most programmable scientific calculators to follow. But they also clearly borrow from the fabulous HP calculators that came before them.
The programming instructions of this calculator include flags (which could be used for a number of hidden functions as well), indirect addressing, subroutines, ...
I actually used this calculator for quite a while, until its battery pack finally gave up.
There is also a power adapter.
