Outdated Technology in Modern Use: 8 Surprising Real-World Cases

Author:Kristen Update:Mar 21,2025

We're used to upgrading our tech every few years – the latest iPhone, a struggling processor, or a graphics card that can't handle the newest games. Old hardware often gets resold or discarded. But many outdated devices remain surprisingly functional, even indispensable. Here are eight remarkable examples of vintage tech still holding its own.

Retro Computers Mining Bitcoin

Believe it or not, a 1982 Commodore 64 can mine Bitcoin. However, its 8-bit, 1 MHz processor manages a paltry 0.3 hashes per second. An RTX 3080 GPU, for comparison, handles 100 million hashes per second. Mining a single Bitcoin on the C64 would take roughly a billion years.

Similarly, YouTuber stacksmashing mined Bitcoin using a 1989 Nintendo Game Boy, connected to the internet via a Raspberry Pi Pico microcontroller. The Game Boy achieved 0.8 hashes per second – slightly faster than the C64, but still about 125 trillion times slower than modern ASIC miners. Mining one Bitcoin would take longer than the universe has existed.

In Gdansk, Poland, a Commodore 64C has assisted mechanics for over three decades. It even survived a flood! This 1 MHz CPU, with its mere 64 KB of memory, flawlessly runs custom software for drive shaft calculations, proving older technology can sometimes outlast its modern counterparts.

Vintage Tech as a Bakery POS System

An Indiana bakery has used a Commodore 64 as its point-of-sale (POS) system since the 1980s. Affectionately nicknamed the "breadbox," this online cash register remains reliable, requiring only keyboard label updates for new baked goods – a stark contrast to the frequent software update woes of modern POS systems.

Outdated Systems Managing Nuclear Arsenals

The United States manages its nuclear arsenal using a 1976 IBM computer and 8-inch floppy disks (approximately 80 KB of data). While modernization plans exist, the system's proven reliability keeps it in place.

Similarly, Germany's navy uses 8-inch floppy disks on its Brandenburg-class frigates. Built in the 1990s, these ships rely on this outdated technology. Upgrades involve floppy disk emulators, but nostalgia seems to play a role in preserving the original system.

Windows XP Powers Multi-Billion Dollar Aircraft Carrier

The British aircraft carrier HMS Queen Elizabeth, a multi-billion dollar vessel, runs on Windows XP – support for which ended in 2014. While the Royal Navy assures necessary security measures are in place, this reliance on outdated software is eyebrow-raising.

The British Vanguard-class submarines Victorious, Vigilant, and Vengeance also use Windows XP for intercontinental missile management. These systems remain offline for security, with updates not planned until 2028.

Critical Airport Infrastructure Fails Due to Legacy Software

In 2015, Paris Orly Airport experienced an outage when a computer running Windows 3.1 (a 1992 operating system) crashed. The DECOR software, providing pilots with weather data, failed, causing flight suspensions.

Classic Hardware Used for Cutting-Edge Research

Retro computers like the Commodore 64 find use in educational settings, teaching programming basics and simulating simple physics experiments. Their simplicity makes them ideal for understanding fundamental computing principles.

Nostalgia Keeps Old Systems Alive

Many organizations retain legacy systems due to habit or nostalgia. Maintaining compatibility with existing workflows or avoiding costly upgrades contributes to the enduring value of familiar tools.

These examples demonstrate the surprising resilience of outdated technology across various industries. From gaming consoles mining cryptocurrency to vintage computers guiding global defense, legacy tech proves remarkably durable. While upgrades are inevitable, these systems highlight the enduring value of simplicity and reliability.
