Greetings everyone! Here is MM studio
Now that the Class65 — our previous work, has come to an end,
we still gonna put our original spirit into our new project,
the Class80, a keyboard with a glimpse of the good ol' days.
Retro is a kind of sentiment, Class80 is just like that.With the light retro style design,Class80 reminds me of the days playing “FAMICOM/SNES“
(or what every console you were playing at young age..)
with couple friends. Can you feel the nostalgia?
God, I have goosebumps writing these lines..
Therefore, in the position of the forehead, we use the classic cassette model,
which not only has symmetrical aesthetics, add a lot of retro feeling into it.
Well, except this time you can’t put a cassette in there, but it’s a pretty cool pen tray 
Big size with comfortClass 80 inherits the wide bezel design of Class 65,
which is 39.34cm long, 18.95cm wide and weighs about 3.5kg unbuilt,
believe us, it’s massive...
In addition, in order to meet the ergonomic,
we made a 1.6cm tilted chin and the whole board's typing angle is 7°. 
In the back of class80, we made a slope to maintain the stereoscopic design.
And we also followed the “FAMICOM/SNES“ stripe design to carve parallel lines in the back.
In order to strengthen the board’s theme and break the single
and heavy feeling of the board’s sideview,
we deliberately cnc‘d a tolerance line on it.
Also, we put a Famicom/SNES controller-like weight in the back of the keyboard(same as Class65V2),
which can be take apart from the board too.
Retro colorsThis time on the Class80, we retain the classic E-white of the Class65,
but more than this we also added an E-red which is one of the most representative color of that era.
Meanwhile, the Class80 will have black Translucent PC version available,
what kind of sparks will collide between the PC material
and Class80 remains a question to be found out by you.
KeycapsThis time, we couldn’t let the chance slip to make a set of retro keycaps,
which will be released with the Class80,
so you can purchase the keycaps together when ordering the kit.
The color is close to GMK L9 and U9, but with subtle color adjustments.
Inside the KeyboardThere’ll be both wired and Bluetooth version Class80 this time.
The Bluetooth version’s battery is 5000mAh and it’s also available for customized keymap.
Both version will have Capslock light.
We also improve the inner brass weight design this time by adding screws on it to avoid scraping the bottom case.
The PCB structure is also improved comparing to the Class65.
The single “S” PCB leaf spring structure was changed to Double ”S”,
visually extending the symmetrical feeling, and also retain the original soft typing experience.
At the same time, the Class80 will continue support plateless builds or
– are you ready?
- with plate in gasket mount or top mount (full plate or half plate) for everyone to choose freely.
PS: Wired PCB has hot-swap and Solder version, Bluetooth version only supports hot-swap. 
One last bombshell, as a classic retro kit, how could it be without a buzzer?
*evilsmile*
Yeah, we'll be adding the buzzer sound you normally hear on a retro keyboard to the Class80.

PS: When you are a Class65 buyer, remember controller weight are compatible with the Class80. If you don’t want a new controller weight, you can contact us to deduct the price by the cost of the controller weight (just to make sure: of course you won’t get a new controller weight with the Class80 in this case)
Renders Thank you for your time!
