IBM’s Model F keyboard is highly regarded among keyboard enthusiasts. The buckling spring switch was introduced on a capacitive printed circuit board (PCB) in the early 80’s and is considered the ancestor of mechanical switches. Despite its fame, the Model F keyboard will be gone by the next decade, becoming extremely rare due to outdated technology and can be difficult to use with modern computers. Targeting retro keyboard fans who don’t want to deal with lengthy searches, repairs, or mods, Model F Labs has recreated IBM’s Model F keyboard with modern OS support, and recently released the classic full-size introduced the iconic Buckle Spring Switch to its keyboard. keyboards, and some proprietary form factors.

With tactile buckling of internal springs and flipper clicks against capacitive PCBs, the keys on IBM’s Model F keyboard inspired today’s mechanical switches. Popular with banks, it replaced IBM’s beam spring keyboard with a low-bulk, low-cost design. Early Model F keyboards had keycaps of the same size and were also removable for customization.
By 1985, IBM was making the Model M keyboard. It was also popular among keyboard collectors today, with keys featuring buckle springs on the membrane and reduced manufacturing costs.
However, Model M keyboard keys are generally considered heavier than Model F keys. Model F keyboards are also considered repairable, according to the Model F Labs. A pair of pliers and a screwdriver”, and its “top internal assembly is designed with a steel tab that slides into the bottom internal assembly”.
And while the Model F and Model M (which popularized today’s US keyboard layout) have had their place in keyboard history, the older Model F has become harder to find (IBM and Lexmark’s original Many of the employees revived the Model M under the Unicomp brand). ).
The Register said: [than Model M keyboards]And there’s even worse news. if you can find [80286-based IBM] PC/AT keyboards use a 5-pin DIN connector and require only a passive adapter to convert to PS/2 format.
“original [IBM Personal Computer] and [IBM Personal Computer XT] The keyboards use the same connector, but different protocols,” continues The Register. [80286-based IBM PC/AT] If you’re even more lucky, there’s a slider switch underneath that lets you choose between PC mode or AT mode. “
Future Model F
Since 2017, Model F Labs has been recreating Model F keyboards through a group of dedicated keyboard enthusiasts. My job involves creating CAD files, working with PCB and product designers, developing capacitive controllers, and learning different keyboard materials. Designed to work with personal devices that were almost unimaginable in the ’80s, the company’s keyboards work with Windows, Mac, Linux, Android, and iOS and connect via a detachable USB-A cable. It says it will. Due to the low production numbers, Model F Labs says they don’t know how long each keyboard will be in stock.
As of April 1st, Model F claims to have sold $2,454,000 worth of keyboards and unveiled a new design on Friday. Compared to Model F Labs’ original recreations of the numeric keypadless F62 Kishaver and F77, the new model has a more modern layout and design and offers a more niche form factor.
First there is the classic style F104 Model F and its smaller version, the Ultra Compact F104 Model F. With a full-size layout and the option to choose a vintage or vibrant chassis color such as red or teal, it looks amazingly versatile. Unlike a true Model F keyboard with a plastic chassis, the Model F Labs recreation uses a (painted or powder coated) aluminum case. This should give the keyboard a vintage weight, but his website for Model F Labs doesn’t list weights or dimensions for the new keyboard. The company also uses dye-sublimation PBT keycaps that are made with newly made injection molds.
“The layout and case of these regular/full size Model F boards are modeled after the later produced Model M keyboard and its more standardized/modernized layout, but with the same Model F internal components and XT quality sublimation. We’re using the type keycaps from the original F62/F77 project,” said an announcement from Model F Labs to unveil the new keyboard.
