With the tactile buckling of the internal spring and the click of the flipper against the capacitive PCB, the keys in IBM’s Model F keyboards inspired today’s mechanical switches.
IBM’s Model F keyboards are prized among keyboard enthusiasts. Introducing buckling spring switches over a capacitive printed circuit board (PCB) in the early 80s, they’re considered the grandfather of mechanical switches. Despite their prestige, Model F keyboards were no more by the following decade and, due to outdated technologies, have become very rare and can be tough to use with a modern computer. Targeting retro keyboard fans who don’t want to deal with long searches, repairs, or mods, Model F Labs recreates IBM’s Model F keyboards with modern OS support, and it recently introduced the iconic buckling spring switches in a classic full-sized keyboard, as well as some unique form factors.
“Much of the design follows in the footsteps of old Model F keyboards, though these are not exact replicas of a 4704 banking keyboard or any other old keyboard,” Model F Labs’ website says. “The firmware and hardware components are completely modern and do not use IBM chips or firmware.”
