I snagged a blue switch 3178 off of eBay last week. It got here yesterday, and I cleaned it up and put a universal xwhatsit I also got off eBay into it.

The keyboard was really clean as used, unrefurbished keyboards go:

This is after I cleaned it, but it didn't look at all worse than this before; I only gave the case a light rubbing with a wet paper towel and ran the keys through denture cleaner - except for the spacebar.

It was, AFAICT, originally built with neoprene foam, and that hadn't deteriorated at all. (The unit is dated 34-1986.) All I did to the keyboard itself was blow the dust bunnies out of it, though this is after the controller replacement.

The backplate shows almost zero corrosion.

I used pandrew's fork via his online configurator to build and load QMK on it. The original firmware was for a different keyboard, but I managed to get it reflashed easily enough. After a few iterations through the layout editor, here's what I would up with for layer 0:

...and layer 1:

...and layer 2.

The idea is that layer 0 is stock PC/Mac, with the </> key repurposed for LGUI and the backtab key repurposed for RMENU, and Attn used for Escape; Dup is Home, and Field Mark is End. The far lower left key is a function shift, with Fn-[1 through =] being PF1-PF12, Fn-keypad being PF13-PF24 (both as printed ont eh front of the keys), Fn-up/Fn-down being PgUp and PgDn, and Fn-Space being a firmware access: Fn-Space-R is reset, Fn-Space-D is Debug, and Fn-Space-E is reset EEPROM.

I use the clicker key (the one to the right of the Fn key) for the solenoid control (press to toggle, Fn-press to reset solenoid parameters), and Fn-right and Fn-left to lower and raise the solenoid duration. Al in all, it's a functional layout, and one I think I'll find quite usable.
