We often upgrade our technology every few years, whether it's the latest smartphone, a lagging processor, or a graphics card that can't keep up with new games. Old hardware typically finds its way to resale markets or, unfortunately, landfills. However, many outdated devices remain functional and even essential in unexpected ways. Here are eight remarkable examples of how vintage tech continues to prove its worth.

Retro Computers Mining Bitcoin
Image: x.com
An enthusiast showcased the potential of the Commodore 64, a 1982 computer, to mine Bitcoin. However, don't get too excited—it manages only 0.3 hashes per second due to its 8-bit, 1 MHz processor. In contrast, an RTX 3080 GPU processes 100 million hashes per second. At this rate, earning one Bitcoin with the C64 would take around a billion years.
Another YouTuber, stacksmashing, attempted to mine Bitcoin using a 1989 Nintendo Game Boy. By connecting the console to the internet through a Raspberry Pi Pico microcontroller, he successfully ran a mining program. The Game Boy achieves 0.8 hashes per second, slightly outperforming the C64 but still about 125 trillion times slower than modern ASIC miners. To mine one Bitcoin, the Game Boy would require more time than the universe has existed.
A Reliable Mechanic’s Assistant Since the '80s

In the Polish city of Gdansk, a dependable Commodore 64C has been assisting mechanics for over three decades. Surviving even a flood, this computer continues to perform calculations for drive shafts with precision. This relic demonstrates that sometimes older technologies can outlast their modern counterparts. With a 1 MHz CPU and only 64 KB of memory, the C64C efficiently runs custom software developed by the business owner.
Vintage Tech as a Bakery POS System

A bakery in Indiana has relied on a Commodore 64 as a point-of-sale (POS) system since the 1980s. Affectionately known as the "breadbox," this computer functions as an online cash register. Unlike modern POS systems that often struggle with software updates, the C64 has remained reliable, requiring only updated keyboard labels for baked goods.
Outdated Systems Managing Nuclear Arsenals

Surprisingly, the United States manages its nuclear arsenal using an IBM computer from 1976, which uses 8-inch floppy disks capable of storing around 80 KB of data—less than the average instant message. Although modernization plans are in place, the current system remains in use due to its proven reliability.
Similarly, Germany's naval fleet uses 8-inch floppy disks on its Brandenburg-class frigates. Despite being built in the 1990s with state-of-the-art weaponry, these ships still rely on outdated storage technology. Efforts to upgrade include installing floppy disk emulators, though nostalgia appears to keep the original system in use.
Windows XP Powers Multi-Billion Dollar Aircraft Carrier

The British aircraft carrier HMS Queen Elizabeth, costing billions, operates on Windows XP, an operating system whose support ended in 2014. Although the Royal Navy claims to have implemented all necessary security measures, this reliance on outdated software raises concerns.
Similarly, Britain's Vanguard-class submarines, Victorious, Vigilant, and Vengeance, use Windows XP for intercontinental missile management. These systems remain offline for security reasons, but updates are not planned until 2028.
Critical Airport Infrastructure Fails Due to Legacy Software

In 2015, Paris Orly Airport faced a failure when a computer running Windows 3.1, a 1992 operating system, crashed. The DECOR software, responsible for providing pilots with weather data, stopped functioning, necessitating flight suspensions for safety reasons. Users humorously suggested that the computer simply wanted to upgrade to Windows 95.
Classic Hardware Used for Cutting-Edge Research
While not mentioned in the original text, there are numerous instances where classic hardware is repurposed for scientific research. For example, retro computers like the Commodore 64 have been used in educational settings to teach programming basics or simulate simple physics experiments. Their simplicity makes them ideal for understanding fundamental computing principles.
Nostalgia Keeps Old Systems Alive
Beyond practical applications, many organizations retain legacy systems out of habit or nostalgia. Whether it's maintaining compatibility with existing workflows or avoiding costly upgrades, these decisions highlight the enduring value of familiar tools.
These examples highlight how outdated technology continues to serve vital roles across various industries. From gaming consoles mining cryptocurrency to ancient computers guiding global defense systems, legacy tech proves remarkably resilient. While eventual upgrades may replace them, these devices remind us of the lasting value of simplicity and reliability.
