Isn't this the one that was on ebay for 1,200 bucks?
Quite interesting switches, looks like Keytronic Tactile foam and foil, but with an MX stem. How does the sensing work? Is it capacitive or conductive? Seems like it would be capacitive, but the ribbon cables make me think conductive.

Yup! This one seems quite interesting though. How does it feel?JP! wrote: ↑26 Apr 2019, 18:39Looks like that one is still for saleLbibass wrote: ↑26 Apr 2019, 16:15Isn't this the one that was on ebay for 1,200 bucks?

Without a doubt, the worst feeling board I’ve ever used. No elitism, run of the mill modern domes feel much better.
Granted some of that might be related to the rubber sheet deteriorating with time.
Maybe I’ll go more into detail about the story behind this keyboard later (if anyone cares to hear it). Not the history of the board itself but rather how I crossed paths with it briefly. It’s not really interesting so much as it is embarrassing.

Ouch. Were you expecting Alps plate springs?

Boy, that sucks. Still, it looks very nice.
I would love to hear more about it!

Hi, did you ever talk about this board.
Are these switches alps capacitive foam switches with rubber shield

Do the keycaps have standard Cherry stabilizers? If so perhaps a new plate and PCB can be made.

Here is the patent for alps foam and foil with rubber collar I remember seeing.

I have no idea if this is the same switch
