RCL-58 is a faithful recreation of the TI-58, the little sister of the TI-59 and 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-58 finally made programming personal, portable and fun.

RCL-58 implements all the powerful scientific/statistics functions and programming capabilities of the TI-58. In addition, it includes:

• Full help support (and a programming tutorial)
• Implementation of the alpha-numeric printer
• Full Master Library support
