About this app
Emulator for the TI-59, TI-58C Calculator and the unreleased TI-59C.
Emulate a 1977 vintage Texas Instruments TI-58/58C/59 calculator. This programmable emulator lets you load/save programs, it includes an implementation of the original Master Library module and many other modules (Leisure, Math, Surveying, Electrical, Aviation, Marine).
The ti5x application does aim for 100% authenticity even if not possible in all cases. Yet, it supports many undocumented features from the original calculator like the HIR registers and the /DSZ nn 51/ (decrement no-jump) instructions.
With the current version it is possible to play some famous games. And many original programs are running without modification.
