TI Programmable 58 - powerful but always losing memory

This calculator was a milestone in terms of programming capabilities, but not a success.
It was soon (1.5 years later, 1979) replaced with a similar calculator model but with a persistent memory - the TI-58C.
There was also a big brother with more memory and a magnetic stripe reader, the TI-59.
Both can be upgraded with special modules, e.g. a mathematics cartridge, or even custom roms for aviation.

Compared to other TI calculators of the same era, battery compartment is different (see the two latches/clips inside), battery pack BP-1A differs from comparable battery packs (e.g. for the TI-57) also.
Don't miss the "cleaning a TI-59" page from Marek Czeszek if you're a collector of these wonderful devices.
