Retro Computers Mining BitcoinImage: x.com

A surprising demonstration showcased a 1982 Commodore 64 mining Bitcoin, albeit at a glacial 0.3 hashes per second due to its 8-bit, 1 MHz processor. This pales in comparison to an RTX 3080 GPU's 100 million hashes per second – mining one Bitcoin would take roughly a billion years! Similarly, a YouTuber mined Bitcoin with a 1989 Game Boy, achieving 0.8 hashes per second via a Raspberry Pi Pico, still vastly slower than modern ASIC miners.

In Gdansk, Poland, a Commodore 64C has aided mechanics for over three decades, even surviving a flood! This 1 MHz, 64 KB machine flawlessly handles drive shaft calculations using custom software, highlighting the longevity of robust, simple technology.

Vintage Tech as a Bakery POS SystemImage: x.com

An Indiana bakery has utilized a Commodore 64 as a POS system since the 1980s. Affectionately dubbed the "breadbox," this reliable cash register, requiring only occasional keyboard label updates, outperforms modern systems prone to software glitches.

Outdated Systems Managing Nuclear ArsenalsImage: x.com

Incredibly, the US manages its nuclear arsenal using a 1976 IBM computer and 8-inch floppy disks (approx. 80 KB storage). While modernization is planned, the system's reliability ensures its continued use. Similarly, German Brandenburg-class frigates, despite modern weaponry, rely on 8-inch floppies. Upgrades involve emulators, but the original system persists.

Windows XP Powers Multi-Billion Dollar Aircraft CarrierImage: x.com

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 While the Royal Navy assures security measures are in place, this reliance on outdated software raises concerns.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

Critical Airport Infrastructure Fails Due to Legacy SoftwareImage: x.com

A 2015 failure at Paris Orly Airport, caused by a Windows 3.1 crash (1992 OS), highlighted the risks of legacy software. The DECOR weather data system failure led to flight suspensions.

Classic Hardware Used for Cutting-Edge Research

Retro computers, like the Commodore 64, find continued use in education, teaching programming fundamentals and simulating basic physics. Their simplicity aids in grasping core computing concepts.

Nostalgia Keeps Old Systems Alive

Beyond practical reasons, many organizations maintain legacy systems due to familiarity or habit, highlighting the enduring value of established workflows and avoiding costly transitions.

These examples showcase the surprising resilience of outdated technology across various sectors. From gaming consoles mining cryptocurrency to aging computers guiding global defense, legacy tech proves remarkably durable. While upgrades are inevitable, these systems highlight the enduring value of simplicity and reliability.
