Buying a Texas Instruments TI-65 Computer System for Scientific Calculation and Programming: A Thorough Analysis

The Texas Instruments TI-65 calculator is a graphing calculator and computer system designed for mathematical calculations, statistical analysis, and even simple programming. This analysis will present an unbiased examination of its key advantages and disadvantages to help decide if this calculator is a good investment.

1. Programming capabilities: The TI-65 offers a robust programming environment through its unique BASIC operating system and extensive library of functions. This makes it ideal for complex mathematical and scientific projects.

2. High Memory: It has 21 KB of ROM memory and 32 KB of RAM, allowing extensive data manipulation and program storage.

3. Graphing capabilities: The TI-65 produces high-quality 3D graphs with various color schemes and an option to trace the graph for better visual comprehension of mathematical functions.

1. Complexity and Learning Curve: Compared to other Texas Instruments calculators, the TI-65 has a more sophisticated operating system, which might make it difficult for beginners.

2. Size and Weight: The calculator is significantly larger and heavier than most modern calculators due to its IBM PC-compatible capabilities and expansive programming environment.

3. Power Source: The calculator runs on rechargeable batteries and can be powered through a dedicated AC adapter, adding more complexity to its power management.

The TI-65 calculator is an excellent investment for individuals requiring advanced graphing and programming capabilities, working on intricate mathematical projects, or individuals looking for an educational challenge. However, its high cost, complexity, and power requirements might deter casual calculator users. We recommend considering the TI-65 if your primary calculator needs come from complex mathematical calculations, scientific projects, or learning programming.

Base your decision on your specific requirements. If you value advanced graphing, sophisticated programming, high memory, and are comfortable with a more significant investment and complexity, we recommend the Texas Instruments TI-65 calculator. Otherwise, consider other options with more streamlined features and a lower learning curve.

Details:

Obviously have been abused by the previous owner FYI I am second owner of this calculator listing unless specify otherwise. Does not necessarily equate to working. Solar and battery power those batteries are replaced as well. Even if the calculator is dual power .e.

Enter number sand perform calculations in octal, decimal or hexadecimal number bases. That's a real plus for repetitive and complex calculations. OAS algebraic operating system allows entry of problems as they are normally written, left tonight. Keys like the later ti-68.

Other keystroke capabilities include looping/branching,subroutine calls and decision making. This is one of the best ti keystroke programmable calculators made since ti-58/59. Listed as used but sold is no display, mention of even if it turns on or much less works. I despise wasting shipping charges.

I have collected calculators for many years so am familiar with what to look for, has become more valuable, and avoid. I have acquired a tremendous repository of resources, manuals, and information for vintage calculators so can provide some direction to my buyers. Very good to excellent overall cosmetic condition please view pics carefully this one is nearly pristine. As a superb and reliable source for vintage calculator parts.

I have had some unscrupulous airguns buyers in the past who actually removed parts, then claimed was not functioning properly, etc. Have known working defects that prevent the calculator from functioning as it should those calculators would only be listed for parts or not. This an extremely nice collectible and Enif my all-time personal favorites amazingly powerful innovative for its time. Automatic power down aped feature extends battery life.

This listing includes the original ti hard case please see pics. Works perfectly. Applications-oriented guidebook, hard shell carrying case and quick reference guide. I despise things that don't work properly especially when purported to be working.

There'seven a stopwatch/timer to insure your experiments and results are accurate at every step. Scientific functions, including reciprocals, common and natural logarithms, universal powers, polar/ rectangular conversions, roots, factorials, trigonometric calculations, inverses, in degrees, radians or grads. Please see below for this calculators specific features. Though not an expert, I am reasonably knowledgeable and experienced.

The resolution of the timer is one second, the maximum time before an overflow occurs about 40 hours. These include polar/rectangular coordinate conversions, factorials,universal powers, and trigonometric calculations, including inverses, in degrees, rads or grads. Constant memory feature. I inspect all battery contacts of calculators and clean them as much possible so that they are in good working condition.

A ti-37 galaxy it adds both programmable and a timer function. Also, I do not give calculator lessons and there is learning curve for any scientific. Why buy a vintage or any scientific calculator from me when you might have other choices. If I discover anything that might not be working as it should, the listing will include information full disclosure and item likely discounted accordingly.

From the technology use this calculator is a unique composition: housing similar to galaxy. Integration using Simpsons rule. Floating decimal, scientific or engineering notation. New batteries installed.

It takes more time to list each one but that's because I care. In addition to the functions of how do you know it even works then. There is no specific diagnostic routine for this calculator that I am aware of.

Needs new batteries, no or batteries not included really. I despise corrosion especially with electronics. If you message me through a listing and ask, I can provide with that information.
