Texas Instruments Programmable 59 Handheld Electronic Calculator

<< >>
Description
This programmable scientific calculator, introduced in 1977, is more powerful than the TI 57 and TI 58, which were introduced at the same time. It has a black plastic case and an array of forty-five rectangular plastic keys, most of which can assume a dual function. The calculator could be operated manually by pressing keys. It could run a variety of preprogrammed routines from a module inserted in a compartment in the back of the case. Programs could also be entered using a set of keys and stored in one of ten locations (denoted by the letters A through E and A’ through E’). Finally, programs could be entered on magnetic cards inserted into a slot in the right side of the calculator. Fuller instructions for programming are given in a detailed manual that accompanied the calculator (see 1990.3166.01).
A mark below the keyboard reads: TI Programmable 59 (/) Solid State Software. Behind the keyboard is a space that would hold a label for a program from a program module. Behind this is a ten-digit display (it may also show eight digits and a two-digit positive or negative exponent). An on/off key is at the back and a jack for a power supply is on the right side.
A mark on the back of the calculator reads: TEXAS INSTRUMENTS (/) electronic calculator (/) SERIAL NO. (/) 05404761 LTA3577 (/) ASSEMBLED IN USA. Below this is a compartment for a battery pack. A sticker inside it is labeled: TEXAS INSTRUMENTS (/) BATTERY PACK BP-1A. Below this is a compartment for a program module, with no module.
The calculator has a black zippered case with a belt loop. This case has number 1990.0609.01.1. Also included is a black Texas Instruments power adapter (a model AC 9131) with a date stamp of 7709 and number 1990.0609.01.2. A plastic wallet holds the Master Library module, a set of labels for use when using programs on that module, and a pamphlet entitled Programmable TI58/59 Master Library Quick Reference Guide (1990.0609.01.3). A second plastic wallet hold the Leisure Library module, a set of labels for use when using programs on that module, and a pamphlet entitled Programmable TI58/59 Leisure Library Quick Reference Guide (1990.0609.01.4).
