A fascinating experiment showed a 1982 Commodore 64 mining Bitcoin. However, its 8-bit, 1 MHz processor only manages 0.3 hashes per second – a stark contrast to an RTX 3080 GPU's 100 million hashes per second. Mining a single Bitcoin on the C64 would take roughly 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 incredibly slow compared to modern ASIC miners.

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

The billions-of-dollars HMS Queen Elizabeth aircraft carrier runs on Windows XP (support ended 2014). While the Royal Navy assures security measures are in place, this reliance on outdated software raises concerns. Similarly, British Vanguard-class submarines utilize Windows XP for missile management, kept offline for security until planned updates in 2028.

In 2015, Paris Orly Airport experienced a system failure due to a Windows 3.1 crash (1992 OS). The DECOR weather data system's failure temporarily halted flights, highlighting the risks of relying on legacy software in critical infrastructure.

Classic Hardware in Cutting-Edge Research

Retro computers, such as the Commodore 64, find applications in education and research, particularly for teaching programming fundamentals and simulating basic physics experiments. Their simplicity makes them valuable tools for understanding core computing concepts.

Nostalgia's Enduring Influence

Many organizations maintain legacy systems due to familiarity, established workflows, or simply inertia, avoiding the costs and disruption of upgrades. This highlights the enduring power of habit and the perceived value of familiar tools.

These examples show how outdated technology continues to play crucial roles across various sectors. From gaming consoles mining cryptocurrency to aging computers guiding global defense, legacy tech demonstrates surprising resilience. While upgrades will eventually prevail, these systems remind us of the enduring value of simplicity and reliability.
