RCL-59 is a faithful recreation of the TI-59, one of the first and most celebrated programmable calculators.

Released by Texas Instruments in 1977, the same year as the Apple ][ and the TRS-80, the TI-59 finally made programming personal, portable and fun.

RCL-59 implements all the powerful scientific/statistics functions and programming capabilities of the TI-59. In addition, it includes:

  • Full help support (and a programming tutorial)
  • Implementation of the alpha-numeric printer
  • Saving and loading of programs
  • Sharing of programs (by exporting/importing them through email)
  • Full Master Library support
