Re: 1990 Chicago Tribune article on keyboards interviewing Key Tronic, Northgate and IBM managers

He found a company in Japan that made key switches with the sound and feel he liked. The feel is like IBM`s, but the click is louder. Hmm, I wonder what company this could be. 8-) Great article, interesting to see the small enter was a deliberate choice and that clicky vs silent rivalries were just...

Re: F62+F77 orders now open! New Kishsaver+Industrial Model F Keyboards

I think it's fair to have this discussion, since the greed vs community thing has been going on for years in keyboard communities. I also think this is an odd bone to pick, given how much Joe has done over the years for the hobby. It's one thing to bring up something like the 4k SSK respectfully and...

Re: building 60% keyboard with vintage switches

These look fantastic, it's cool to see unique switches being used in custom builds. Would love to see a typing demo of the Fujitsu and Omron boards if you have them all assembled.

Re: Beamspring keycap yellowing

Like SneakyRobb said, the yellowing ones are most likely replacements from a different factory (Greenock) that used a different formula.

I agree this is a golden age of appreciation, even if prices are a lot higher than they once were for vintage items. We've never had so many options to try for both original and re-creation switches, not to mention ways to trade and share our experiences. It seems most things considered 'eccentric' ...

Re: IBM 5251 - different keycap plastics?

You're right about the manufacturing process changing, especially in EU factories. While these were caps originally made in the late 70s, replacement caps were available well into the 80s. It's possible the ones yellowing are replacements that were manufactured in the Greenock factory, who were noto...
