Why did old PCs have key locks? An LGR Retrospective In the fascinating realm of vintage computing, the presence of key locks on older PCs evokes a mix of nostalgia and curiosity. These mechanisms were a commonplace feature from the mid-1980s until the mid-1990s, serving practical applications that for many have now become obsolete. The video by LGR—"Why did old PCs have key locks? An LGR Retrospective"—delves into the origin and function of these key locks. Initially introduced with IBM's 5170 model in 1984, these locks were designed to secure personal computers, preventing unauthorized access and securing sensitive information. While they generally provided minimal security, their primary role was to deter casual tampering, particularly in office environments where multiple users might have access to the same machine.
Key Functions of the Locks
Key locks served various purposes:
Restricting case access - In certain models, the lock physically prevented the case from being opened, adding a layer of security.
Disabling keyboard input - Some systems only blocked keyboard activity, shorting connections on the motherboard when the key was turned. This approach made it challenging for unauthorized users to interact with the computer, although bypassing the lock was often straightforward for someone determined enough.
Why Did They Fall Out of Favor?
The decline of key locks corresponded with the introduction of more sophisticated software security measures. BIOS passwords and user profiles offered robust protection, rendering the physical locks less relevant for home users. Moreover, the typical home computing environment, where one often shares access only within the family, diminished the need for such features. Today, while laptops still occasionally come with physical locks, such as those offered by Kensington, they are usually optional.
Nostalgic Appeal
Despite their obsolescence, there's a unique charm associated with key locks. Many vintage computer enthusiasts find joy in the nostalgia these devices evoke, reminiscent of an era when technology was simpler yet filled with quirks. Working with computers that feature these locks can remind one not only of the era but also of how security practices in computing have evolved over time. If you share an affinity for retro tech, this video offers an intriguing perspective on a minor yet memorable detail of computing history. As technology continues to advance, it’s interesting to look back at these features and reflect on how they shaped our relationship with computers over the years.
