We're used to upgrading our gadgets every few years, whether it's snagging the latest iPhone, dealing with a sluggish processor, or swapping out a graphics card that can't keep up with new games. Old hardware often finds a second life being resold or ends up discarded.
Yet, many of these outdated devices continue to function and even play crucial roles in unexpected ways. Here are eight fascinating examples of how vintage tech still holds its own.

Retro Computers Mining Bitcoin
Image: x.com
An enthusiast proved that the Commodore 64, a relic from 1982, can mine Bitcoin. But don't hold your breath—it processes only 0.3 hashes per second with its 8-bit, 1 MHz processor. For context, an RTX 3080 GPU can manage 100 million hashes per second. At this pace, earning one Bitcoin with the C64 would take about a billion years.
Another tech-savvy YouTuber named stacksmashing attempted to mine Bitcoin using a 1989 Nintendo Game Boy. By hooking the console up to the internet via a Raspberry Pi Pico microcontroller, he managed to run a mining program. The Game Boy clocks in 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 run longer than the universe has existed.
A Reliable Mechanic’s Assistant Since the '80s

In Gdansk, Poland, a trusty Commodore 64C has been a mechanic's right-hand tool for over three decades. Despite surviving a flood, this computer continues to perform drive shaft calculations flawlessly. This vintage machine, with its 1 MHz CPU and just 64 KB of memory, runs custom software developed by the business owner, proving that sometimes older technologies outlast their modern counterparts.
Vintage Tech as a Bakery POS System

A bakery in Indiana has been using a Commodore 64 as its point-of-sale (POS) system since the 1980s. Affectionately known as the "breadbox," this computer serves as an online cash register. Unlike modern POS systems that often struggle with software updates, the C64 remains 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Outdated Systems Managing Nuclear Arsenals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. While modernization plans are in place, the current system 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 suggested 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, classic hardware often finds new life in 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 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 illustrate how outdated technology continues to serve critical functions across various 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.
