I have always been told to use Dawn. I wonder if that would have damaged the logo?

Definitely.

I got my original Model M for $30 shipped to the USA, and luckily had a friend there to receive it for me and then take it to me when visiting. It was missing 3 or 4 keycaps, but otherwise fine. I'd recommend it. The first Model M I got off of ebay for around the same price was ok, but ...

Really the only reasonable answer.


However, I would suggest the OP read up on the proper care and feeding of a Model M as any $30 'board on e-bay is most likely going to need some TLC.

I like the idea of a keyboard that has dynamically adjustable resistance. Not too sure how I would like the feel though...

I go the packing tape route as well. It has never led me astray. Although I hear, given long enough, the adhesives in the tape will eventually cause pigment migration/smearing issues with regard to the printing on the label.

That was the old IBM, back when they really cared 100% about every piece of tech they put out there. They were truly one of the great engineering forces on the face of the earth in the 20th century.

Buckling spring would be amazing and there would be a lot of benefits including making the keycap weight a bit higher for better feel without making the stem feel wobbly.

Beam spring clicks at the same point of actuation. Buckling spring too as mentioned above.

My wife has a MX Blue (a Leopold numpadless thing) and I can't handle the disconnect between actuation and click. It's even worse than the scratchiness of the movement. I find I miss a lot of keys as I feel ...

I will note that around 1997-1998 or so, the Chinese started cranking out downright atrocious knockoffs of membrane buckling spring boards.

And, Alps clones have existed for over a decade. Cherry clones have existed for a few years now.
