The New Unicomp IBM Model M
I've had my IBM Model M for over 10 years (even though it predates me) and it's been a staple in my computing. Nothing has been more of a staple and a constant in my life than that keyboard.
Unfortunately the left shift key pivot key became loose, and thus the left shift became unreliable. After looking at finding replacement parts, the one place that sells the part...also sells brand new Model M's. Killing two birds with one stone and I just ordered the Unicomp IBM Model M.
Coming from the 139041 model, I gained a Window key (Tux key as you can see) and opted for the larger spacebar.
