TI-59

The TI-59 is a programmable computer among most powerful until in 1980 with a memory of 480 pas de programs and 60 numeric variables (10 registers = 80 pas) adjustable until 960 pas de programs or 100 variables and 160 pas de programs.

Its performances and its price (approximately 300 $) make it gravitational compared to the computers of the time (APPLE II, TRS-80) much more expensive.

It integrates a small reader of memory card to safeguard the programs on fine magnetic cards of approximately 15 × 50 Misters. Video: TI-59 reading of magnetic cards

It is the first computer to integrate a site to add an expander card ROMANIAN removable containing until 5000 pas by module of libraries of programs Texas Instruments, dedicated professional applications or plays.

Its memory is volatile and it is necessary to record its programs on the magnetic cards before extinguishing it. It was possible to buy a cradle integrating a thermal printer PC100.

The computer programming language, although powerful and compatible with the TI-58 and TI-58C, place did not give to a long line and only TI-66 used it thereafter.

Its principal competitors were the Hewlett Packard HP-41 and HP-67.
