Outdated Technology in Modern Use: 8 Surprising Real-World Cases

by Lucy Feb 28,2025

The relentless march of technology sees us upgrading our gadgets every few years – iPhones, processors, graphics cards – with older hardware often resold or discarded. Yet, surprisingly, many outdated devices remain functional and even crucial. Here are eight examples of vintage tech still holding its own:

Retro Computers Mining Bitcoin

A fascinating experiment showed a 1982 Commodore 64 mining Bitcoin, albeit at a glacial 0.3 hashes per second. This pales in comparison to a modern RTX 3080 GPU's 100 million hashes per second. Mining a single Bitcoin on the C64 would take, realistically, billions of years. Similarly, a YouTuber used a 1989 Game Boy (via a Raspberry Pi Pico) to mine Bitcoin, achieving 0.8 hashes per second – still incredibly slow compared to modern ASIC miners.

A Commodore 64C in Gdansk, Poland, has assisted mechanics for over 30 years, even surviving a flood! This 1 MHz, 64 KB machine flawlessly runs custom software for drive shaft calculations, showcasing the longevity of simple, reliable technology.

Vintage Tech as a Bakery POS System

An Indiana bakery has used a Commodore 64 as its POS system since the 1980s. Nicknamed the "breadbox," this reliable cash register avoids the software update headaches of modern systems, requiring only occasional keyboard label updates.

Outdated Systems Managing Nuclear Arsenals

Incredibly, the US manages part of its nuclear arsenal using a 1976 IBM computer and 8-inch floppy disks (approx. 80 KB storage). While modernization is planned, its reliability keeps it in service. Similarly, German Brandenburg-class frigates utilize 8-inch floppy disks, with upgrades involving emulators rather than complete system replacement.

Windows XP Powers Multi-Billion Dollar Aircraft Carrier

The British HMS Queen Elizabeth aircraft carrier, costing billions, runs on Windows XP (support ended 2014). While the Royal Navy assures security measures are in place, this reliance on outdated software is noteworthy. Similarly, British Vanguard-class submarines use Windows XP for missile management, though these systems are offline for security and updates aren't planned until 2028.

Critical Airport Infrastructure Fails Due to Legacy Software

In 2015, Paris Orly Airport experienced a failure when a Windows 3.1 (1992) system crashed, halting weather data to pilots and causing flight suspensions.

Classic Hardware Used for Cutting-Edge Research

Retro computers, such as the Commodore 64, find use in educational settings for teaching programming fundamentals and simulating basic physics experiments due to their simplicity.

Nostalgia Keeps Old Systems Alive

Many organizations maintain legacy systems due to familiarity, established workflows, or the cost of upgrading.

These examples highlight the surprising resilience of outdated technology, performing crucial functions across various sectors. While upgrades are inevitable, these systems demonstrate the enduring value of simplicity and reliability.
