I haven't owned a mechanical keyboard in years, but I found this while thrifting the other day. Cleaned it up, everything seems to work fine.

The only thing that irks me is the spacebar. It sort of teeter totters and only works when I press in the center. Are there supposed to be three switches under it?

Also, is there any way to swap the alt/windows keys at the hardware/firmware level? I prefer the macOS layout and would like to avoid juggling configuration software on each device I own.
