So apparently, Ming-Gih Lam aka dcpedit/dj_edit is on a roll. After the Mod Mmm, a PCB for the IBM Model M, he shared another replacement PCB. The Mission Control PCB was designed to replace all internal components of an IBM Model M122. Only the curved steel backplate is needed for the PCB to be mounted on.
I'm back again with another Model M mod! Similar to my previous Mod Mmm PCB, the Mission Control PCB replaces the internals of the Model M122, the king of battleship keyboards! – dj_edit.
Yep, you heard it right. IBM's buckling spring monster introduced in 1985 is now compatible with your favorite MX switches and keycap sets.
