MM Studio Class 100: The Return of the Terminal Icon

Relive the golden age of computing with the Class 100. Inspired by the legendary DEC VT220-LK201, this full-size keyboard is more than just a typing tool—it’s a technological bridge between iconic 1980s design and today’s cutting-edge mechanical engineering.

A Multi-Sensory Experience

The Class 100 doesn't just mimic retro aesthetics; it captures its soul. Thanks to the integrated solenoid and buzzer, every keypress can be accompanied by the characteristic metallic "click" and physical feedback typical of vintage terminals. It is a tactile and auditory experience that no standard modern keyboard can replicate.

Engineered for Comfort: Isolated Top Mount

Forget the stiffness of old membrane keyboards. The Class 100 utilizes an innovative Isolated Top Mount system with silicone gaskets ("socks"). This design eliminates unwanted vibrations, providing a soft bounce and a clean sound signature—perfect for long typing sessions.

Key Features:

• Modular Design: Choose between the clean look of the Winkeyless (WKL) version or the practicality of the Winkey (WK) version.

• Customizable Legend Strip: A polycarbonate insert with LED indicators that faithfully recalls the control panels of early computers.

• Premium Materials: A massive 6063 aluminum case featuring sandblasted brass internal and external weights, reaching a total weight of over 4kg.

• Functional Badge: A 3u magnetic enameled brass badge that can be replaced with 3 additional keys, ensuring you never have to sacrifice productivity.

• Fully Programmable: Full QMK and VIAL support to remap every single key and create complex macros.

What’s in the Kit:

1. Aluminum Case (Top & Bottom)
2. Brass Weights (Internal and External)
3. Hotswap or Solder PCB (Your choice)
4. Solenoid and Buzzer Module with dedicated Daughterboard
5. Gasket set (Silicone Socks) and rubber feet
6. MM Studio Hard Carrying Case

The Expert's Take:

The Class 100 is an "end-game" board for those who love full-size layouts. It is rare, heavy, and incredibly satisfying to use. If you are looking for the definitive centerpiece for your desk that blends nostalgia with enthusiast performance, you’ve found it
