Maybe put them up for trade here and see what offers you get?
Not a bad idea. You're right the new Gaterons will definitely bring down the demand for blacks even quasi-vintage blacks like these (~'02). I'm going to start a separate thread FS/FT in the classifieds.
Anyone else have any ideas on projects or hacks for these? Or, projects using the switches or parts? The board has MX Blacks circa '02-ish, and omron switches for the mouse buttons. The switches have red LED's which could be interesting for some folks.
I was going to try using the switches in an Infinity board on MD right now but it doesn't appear to support LEDs, and sourcing a keycap set for LED keys would be challenging anyway due to the layout on that board (there is a standard layout option but it really just gives you standard-sized keys on the bottom row, there are other non-standard keys on that board).
