HP-71

The Hewlett-Packard HP-71 and HP-84 are two iconic handheld calculators released by HP in the late 1970s and early 1980s, respectively. These calculators were known for their advanced features, sleek designs, and high-quality construction.

The HP-71 was HP's first programmable calculator, featuring a built-in ROM that allowed users to store and recall up to 128 user-defined functions. This calculator could perform a wide range of mathematical operations, including trigonometric, exponential, logarithmic, and statistical functions. Its keyboard was designed for ease of use, with large, well-spaced keys and a clear, easy-to-read display. The HP-71 also featured a built-in constant memory, which allowed users to store and recall constant values.

The HP-84, released a few years later, was an upgrade to the HP-71 and featured a number of improvements. It had a larger, higher-resolution display that was easier to read, even in low-light conditions. The HP-84 also had more memory, allowing it to store up to 256 user-defined functions. This calculator could perform even more complex mathematical operations than the HP-71, including matrix calculations and complex number arithmetic. Additionally, the HP-84 had a built-in clock and calendar, making it a versatile tool for both personal and professional use.

Both the HP-71 and HP-84 were built with high-quality materials and construction. They had rugged, all-metal cases that were designed to withstand the rigors of daily use. The keys were tactile and responsive, making data entry a pleasure. The calculators also had long battery life, allowing users to work for hours without needing to recharge.

In summary, the Hewlett-Packard HP-71 and HP-84 were advanced, feature-rich calculators that were prized for their sleek designs, high-quality construction, and ease of use. They were versatile tools that could handle a wide range of mathematical operations, making them essential for scientists, engineers, and students. With their large, easy-to-read displays, ample memory, and long battery life, these calculators were truly ahead of their time.

The Hewlett-Packard (HP) HP-71 and HP-84 are vintage handheld calculators released in the early 1980s. These calculators were revolutionary for their time due to their programmability and large, easy-to-read displays. Here are some pros and cons of buying an HP-71 or HP-84 calculator today:
