I'm kind of the reverse of this, I started with an IBM Selectric II, then refurbished a Model M 122 Tetminal Keyboard, and now I am trying to build a 100% Keyboard with macros to mimic the matter aspects of the Model M 122, and switches that feel as close to the Buckrling Springs, with SA keycaps to mimic the Selectric. Matias Quiet Clicks FYI feel the closest, but finding a board that fits the Alps-like switches is unobtanium.
