IBM SK-8845 Ultranav USB keyboard
IT’S GOT THE RUBBER MOUSE NIPPLE AND EVERYTHING! Fucking lol, that’s amazing. I’m tempted to go that route just for pure nostalgia sake… I should probably avoid anything that’s long-discontinued though, as I probably wouldn’t be able to repair it if it stopped working, and then I’d be back at square one.
Cherry MX Brown switches
The actual post in the center of those is brown, right? I popped a key off, and the ones in mine are kind of a yellow-orange color like the Helios v2 ones you posted, but with a black housing. The noise they produce is pretty much entirely from the bottom of the keycap hitting plastic when it bottoms out (which is significantly dampened by rubber o-rings I added to it) and then another plastic-on-plastic sound on release… which maybe that is the components of the switch hitting itself? Most of the noise is from release. Slowly depressing a key until it bottoms out, then slowly releasing it so that all of the plastic-on-plastic collisions are super gentile, a keystroke makes virtually no noise.
A real tragic loss: it seems the road was damaged. :(
