A Comparison of TI-2550II and TI-85 Calculators: Which One Should You Buy?

The TI-2550II and TI-85 are both graphing calculators manufactured by Texas Instruments. Both models have their unique features, advantages, and disadvantages. In this comparison, we will discuss the key differences between these calculators to help you make an informed decision.

- TI-2550II: It has a grayscale, segmented display with 112 x 84 pixels resolution.

- TI-85: It boasts a monochrome, high-resolution reflective LCD screen with 160 x 128 pixels resolution.

Advantage of TI-85: The higher resolution display offers clearer text and graph visualization.

- TI-2550II: It offers 24 KB of RAM and 72 KB of ROM.

- TI-85: It comes with 128 KB of RAM and 128 KB of ROM.

Advantage of TI-85: The larger memory capacity allows for more complex programs and data storage.

- TI-2550II: It provides basic graphing capabilities, including up to 11 graphing functions, 6 traceable points, and 2 Y-intercepts.

- TI-85: It supports up to 12 graphing functions, 10 traceable points, and 2 Y-intercepts.

- TI-2550II: It comes with built-in BASIC programming language.

- TI-85: It supports both BASIC and TI-BASIC programming languages.

Advantage of TI-85: The availability of TI-BASIC offers more programming capabilities and flexibility.

- TI-2550II: It does not have any direct connectivity options.

- TI-85: It offers a built-in infrared port for data exchange and communication with other TI-85 calculators.

- TI-2550II: It has a battery life of approximately 50 hours.

- TI-85: It offers a battery life of approximately 100 hours.

Advantage of TI-2550II: Its smaller display consumes less power, resulting in a longer battery life.

- TI-2550II: It is generally less expensive than the TI-85.

- TI-85: It is more expensive due to its advanced features.

Both the TI-2550II and TI-85 have their unique strengths. If you prioritize a clear display, larger memory, advanced programming capabilities, and connectivity, the TI-85 would be the right choice. However, if you need a more affordable option with a longer battery life, the TI-2550II is the way to go.

Based on the comparison, if your primary focus is on affordability and a longer battery life, the TI-2550II is the recommended calculator for you. If you require advanced features, such as a high-resolution display, larger memory, and connectivity, the TI-85 would be the better option.

Details:

Second calculator is a older ti 85 which comes with its hard shell cover. The ti 2550ii comes with its case. Requires four AAA batteries and a button battery. This lot has two t.i.

Battery compartment is clean. I do not have a button battery to try it, did put in for fresh AAA and thought that powered up. Unit does not turn on with those batteries and I don't want to force them out. There are two batteries in its battery compartment.

Neither have been tested due to batteries needed.
