A notable experiment showcased a 1982 Commodore 64 mining Bitcoin. However, its 8-bit, 1 MHz processor yields a paltry 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 approximately a billion years. Similarly, a Game Boy from 1989, connected to the internet via a Raspberry Pi Pico, achieved 0.8 hashes per second – still infinitesimally slow compared to modern ASIC miners.

The United States' nuclear arsenal management system relies on a 1976 IBM computer using 8-inch floppy disks (approx. 80 KB storage). While modernization is planned, its reliability maintains its current role. Similarly, German Brandenburg-class frigates use 8-inch floppy disks, with upgrades involving emulators, highlighting the persistence of legacy systems.

The British HMS Queen Elizabeth aircraft carrier, a multi-billion dollar vessel, operates on Windows XP (support ended 2014). The Royal Navy assures security measures are in place, but the reliance on outdated software remains noteworthy. This is echoed in the Vanguard-class submarines' use of Windows XP for missile management, currently offline for security, with updates not planned until 2028.

Retro computers find applications in educational settings, teaching programming fundamentals and simulating basic physics experiments. Their simplicity facilitates understanding core computing principles.

While not explicitly detailed in the original text, the continued use of legacy systems often stems from ingrained practices and a reluctance to disrupt established workflows. The cost of upgrades also plays a significant role.

These examples demonstrate the surprising longevity and continued relevance of outdated technology across various sectors. From cryptocurrency mining to managing nuclear arsenals, legacy tech proves remarkably resilient. While modernization is inevitable, these systems highlight the enduring value of simplicity and reliability.
