The TI-59 is an early programmable calculator, that was manufactured by Texas Instruments from 1977. It is the successor to the TI SR-52, quadrupling the number of "program steps" of storage, and adding "ROM Program Modules" (an insertable ROM chip, capable of …

The TI-59 was the first "real" programmable calculator in the world - you could actually use it to perform some useful work, like solving the system of linear equation, finding the zero of a function or even playing a Hi-Lo game... or the game of chess.

The TI-59 Programmable calculator makes full use of the TMS0500 Building Blocks and a closer look at the PCB (printed circuit board) of the TI-59 reveals a total of nine PMOS (P-channel Metal–oxide Semiconductor) chips:

The Texas Instruments Ti-59 has small magnetic cards that can store programs and data when this programmable calculator is off. This Texas Instruments calculator uses ROM Program Modules, an insertable ROM chip capable of holding 5000 program steps.

2020年8月23日 · TI-59于1977年5月推出，使用4位处理器TMC 0501，可编程的软件模块多达5000个程序，包含矩阵计算、线性方程的解、复杂算法、金融和日历计算等，甚至还有一个简单的游戏，使TI-59成为许多专业人士的有用工具。 TI-59还有个特色——磁卡，用户可以把它塞进LED显示屏右边的一个小槽里，程序通常被存储在磁卡上，这样用户就不必每次打开计算器就输入 …

Texas Instruments, Inc invented the electronic handheld calculator in 1967. Originally conceived as a product that would create worldwide demand for the microchip, the handheld calculators became a powerful tool for engineers and businessmen.

Most common troubles with TI–59 calculators are caused probably by their magnetic card readers; this article should help you solve these problems. Below, I've only included repairs that do not require breaking into electronics (without soldering, to be precise).

I have recently obtained permission from Texas Instruments to post scans of pre-1984 calculator documentation here. Here are the manuals that I have so far managed to scan.

2003年8月30日 · With up to 960 program steps and 100 data memories, the TI-59 was the flagship of TI's calculator line at the height of the 1970s calculator era. The TI-59 remained in production until 1983. Although Texas Instruments went on to create newer models, the market for powerful and expensive programmable calculators had largely disappeared with the ...

TI—59型计算器是携带方便的手持式计算器,它小巧精致,功能较强.为了增多功能而不使机键过多,通过第二功能键2nd和反向功能键INV使键盘能只靠45个机键而完成108种不同的操作,使用者可以灵活地编排程序.它不仅能够进行基本算术运算和代数函数,还能够把使用者所 ...
