IBM's Legendary Model F Buckling Spring Keyboard Reinvented, Now Available To Order
Until very recently the Model F was a nearly extinct, rare beast, only found in retro graveyard revivals with keepers of the faith, or the lucky few with access to dinosaur, left-behind stockpiles from the big hair days of computing. That is until one Joe Strandberg, a Cornell University grad and said keeper of the faith, decided he wanted to resurrect the Model F in all its glory.
Joe remembered the glorious keyboard well, not just because it was the golden era birth of the PC, but because it quite literally, in his opinion, was the best there ever was. He used to restore old original IBM Model F keyboards and learned the ins and outs of the battleship build quality and internal mechanics of the keys. So one day, he took it upon himself to begin the process of literally re-tooling, redesigning, and building a new Model F, exactly to IBM's specs.
This wouldn't be any 3D printed replica either, but a fully tooled, ready-for-production unit. Strandberg notes that a 3D printed version couldn't hold up to the stresses of the buckling spring and its mechanics. As you can see in the figure above, there's literally a spring inside each key switch and that spring buckles -- hence the "buckling spring" design naming -- which then presses down on a plastic paddle below and actuates a key stroke on the PCB underneath. It's a simple, perhaps primitive design, yet oh-so satisfying in both its audible and tactile feedback. Cherry has made big business of its Cherry MX line of key switches, with different tactile feel and both clicky and non-clicky switch types, but purists argue there's nothing that's quite like the buckling Model F.
If the Model F has you intrigued, and you'd like to try a buckling spring keyboard, but the high price and layout don't work for you, don't fret -- the Model F isn't your only option. Unicomp has been reproducing updated IBM Model M and similar style keyboards using buckling spring key switches true to IBM's design for years, and some models are available for under $100.
