"8 Surprising Cases of Outdated Tech Still in Use Today"

We're all familiar with the cycle of upgrading our technology every few years, whether it's the latest iPhone, a struggling processor, or a graphics card that can't keep up with new games. While old hardware often ends up resold or discarded, many outdated devices continue to function and prove indispensable in unexpected ways. Here are eight fascinating examples of how vintage tech still holds its ground.

Retro Computers Mining Bitcoin

An enthusiast demonstrated that the Commodore 64, a computer from 1982, could mine Bitcoin. However, with its 8-bit, 1 MHz processor, it processes only 0.3 hashes per second. For context, an RTX 3080 GPU handles 100 million hashes per second. At this pace, earning one Bitcoin with the C64 would take about a billion years.

Another YouTuber, stacksmashing, tried mining Bitcoin using a Nintendo Game Boy from 1989. By connecting the console to the internet via a Raspberry Pi Pico microcontroller, he managed to run a mining program. The Game Boy operates at 0.8 hashes per second, slightly faster than the C64 but still about 125 trillion times slower than modern ASIC miners. To mine one Bitcoin, the Game Boy would need to work longer than the universe has existed.

A Reliable Mechanic’s Assistant Since the '80s

In the Polish city of Gdansk, a trusty Commodore 64C has been assisting mechanics for over three decades. Despite surviving a flood, this computer continues to perform calculations for drive shafts flawlessly. With its 1 MHz CPU and just 64 KB of memory, the C64C effortlessly runs custom software developed by the business owner, proving that sometimes older technologies can outlast their modern counterparts.

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. Known affectionately as the "breadbox," this computer serves as an online cash register. Unlike modern POS systems, which can be prone to software update issues, the C64 remains reliable, with only the keyboard labels for baked goods needing updates.

Outdated Systems Managing Nuclear Arsenals

Believe it or not, the United States manages its nuclear arsenal through 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. While plans exist to modernize the system, the current setup persists due to its proven reliability.

Similarly, Germany's naval fleet employs 8-inch floppy disks aboard its Brandenburg-class frigates. Despite being built in the 1990s with state-of-the-art weaponry, these ships rely on outdated storage technology. Efforts to upgrade include installing floppy disk emulators, though nostalgia seems to keep the original system alive.

Windows XP Powers Multi-Billion Dollar Aircraft Carrier

The British aircraft carrier HMS Queen Elizabeth, costing billions, runs on Windows XP, an operating system whose support ended in 2014. Although the Royal Navy insists all necessary security measures are in place, such 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 aren't planned until 2028.

Critical Airport Infrastructure Fails Due to Legacy Software

In 2015, Paris Orly Airport experienced 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, forcing flight suspensions for safety reasons. Users humorously remarked that the computer simply wanted to upgrade to Windows 95.

Classic Hardware Used for Cutting-Edge Research

While not explicitly mentioned in the original article, there are numerous cases where classic hardware is repurposed for scientific research. For instance, 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 purely 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 underscore how outdated technology continues to serve critical functions across industries. From gaming consoles mining cryptocurrency to ancient computers guiding global defense systems, legacy tech proves surprisingly resilient. While upgrades may eventually replace them, these devices remind us of the enduring value of simplicity and reliability.
