Hi community! This is MM Studio and we r bringing u our newest GB: Class100
Brief intro: Fullsize keyboard with Solenoid/Buzzer, PC legend strip with OG VT220-LK201 look design. Replaceable 3u top badge.
DEC VT220-LK201 with PC legend strip version:
IntroductionThe Class100 returns to the roots with a classic 100% full-size layout.
We've designed a modular top-right section that houses a 3u brass enamel badge,
which can be easily swapped out for three functional 1u keys.
Features a PC (Polycarbonate) accent strip with legend inserts,
inspired by the LK201, also with classic 3 indicator leds on old full size board.
As always, MM Studio's classic solenoid and buzzer are integrated into the Type-C daughterboard located under the top strip. The daughterboard features a custom orange spray coating, designed to faintly peek through the translucent PC strip for a layered visual effect.
Utilizing the PC material's light diffusion, the Legend Strip is backlit by a full-length RGB strip and features 3 classic indicator lights.
The bottom weight design draws direct inspiration from the cover art of the classic VT220 Reference Guide—a visual motif we have also carried over to the Class 100’s packaging and instruction manual.
（Please note that the enamel infill color on the weight will be adjusted for the final Group Buy units. While the prototype photos show a bright red, the mass production units will use a Deep Burgundy (Original Dark Purple-Red) to match the original color.）
Class 100 utilizes a classic Isolated Top Mount system.
We use custom-molded silicone socks, which are then secured using shoulder limit screws. This ensures consistent alignment without over-stiffening the typing feel.
And also the design allows for flexibility. You can choose not to install all the screws, allowing the silicone caps to act as a Gasket Mount for a softer experience.
For those who prefer a livelier spacebar, you can remove the mounting screws specifically on either side of the spacebar to adjust the local flex and acoustic feedback.
