-Dubleshoot ABS mostly, except Ctrl, Alt, Caps Lock, maybe Tab, Shift. Those are pad printed. Ctrl, Alt, Shift have colored legends: red, green, and blue respectively.
-DIN-5, AT/XT switchable
-Tested, every switch works fine.
-Some dark grey stripes don't show up (especially on the back side) quite well on the pics, tried to erease with some magic ereaser. Looks quite better after doing so.
