A notable 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 hashes per second. Mining a single Bitcoin on the C64 would take approximately a billion years. Similarly, a YouTuber used a 1989 Nintendo Game Boy (via a Raspberry Pi Pico) to mine Bitcoin at 0.8 hashes per second – significantly slower than modern ASIC miners.

The United States utilizes a 1976 IBM computer, using 8-inch floppy disks (approximately 80 KB), to manage its nuclear arsenal. While modernization is planned, the current system's reliability ensures its continued use. Similarly, German Brandenburg-class frigates, despite modern weaponry, rely on 8-inch floppy disks. Upgrades are underway, including floppy disk emulators, but the original system persists.

The British HMS Queen Elizabeth aircraft carrier, costing billions, runs on Windows XP (support ended in 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 While the Royal Navy assures security measures are in place, this reliance on outdated software is noteworthy.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 reasons until planned updates in 2028.

In 2015, Paris Orly Airport experienced a system failure due to a Windows 3.1 crash, halting weather data provision to pilots and causing flight disruptions.

Classic Hardware Used for Cutting-Edge Research

Retro computers, such as the Commodore 64, find applications in educational settings, teaching programming fundamentals and simulating basic physics experiments. Their simplicity aids in understanding core computing concepts.

Nostalgia Keeps Old Systems Alive

Beyond practical uses, many organizations maintain legacy systems due to familiarity and established workflows, highlighting the enduring value of familiar tools and avoiding costly replacements.

These examples illustrate the surprising resilience of outdated technology, fulfilling critical roles across various sectors. From cryptocurrency mining to global defense systems, legacy tech's simplicity and reliability endure, reminding us of their lasting value. While upgrades are inevitable, these systems highlight the enduring power of proven technology.
