One enthusiast demonstrated Bitcoin mining on a 1982 Commodore 64. However, its 8-bit, 1 MHz processor yields a paltry 0.3 hashes per second, compared to an RTX 3080 GPU's 100 million. Mining a single Bitcoin would take approximately a billion years. Similarly, a YouTuber mined Bitcoin using a 1989 Game Boy, achieving 0.8 hashes per second via a Raspberry Pi Pico – still vastly slower than modern ASIC miners. Mining one Bitcoin would take longer than the universe's existence.

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

The US manages its nuclear arsenal using a 1976 IBM computer with 8-inch floppy disks (approx. 80 KB storage). While modernization is planned, the system's reliability maintains its continued use. Similarly, Germany's Brandenburg-class frigates utilize 8-inch floppy disks, with upgrades involving emulators rather than complete system replacements.

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 While the Royal Navy assures security measures are in place, this reliance on outdated software is noteworthy.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, Britain's Vanguard-class submarines use Windows XP for missile management, remaining offline for security until planned updates in 2028.

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

Classic Hardware Used for Cutting-Edge Research

Retro computers, like the Commodore 64, find use in education for teaching programming and simulating basic physics experiments, their simplicity aiding in understanding fundamental computing concepts.

Nostalgia Keeps Old Systems Alive

Many organizations retain legacy systems due to familiarity, established workflows, or the cost of upgrades, highlighting the enduring value of familiar tools.

These examples highlight the surprising resilience and continued relevance of outdated technology across various sectors. From cryptocurrency mining to global defense, legacy tech demonstrates the enduring value of simplicity and reliability, even as upgrades eventually become necessary.
