I tried making an offer a week ago and he wouldn’t go lower then.
I got a Mitsubishi MP286L laptop that has this same keyboard. The keyboard uses those PCB-mounted Alps switches with the oval sliders
http://deskthority.net/wiki/Alps_low-profile_oval_slider, plus some skinnier ones of the same general type (which I don’t think are on the Deskthority wiki) for the F keys &c.
The keycaps are doubleshot, of the standard Alps-produced type, except for the skinny top keys, which are printed. These are the same type of keycap that were also used on Toshiba laptops of that era. For an example of someone putting them to better use, see
http://geekhack.org/index.php?topic=54857.0 (though Paranoid’s Toshiba laptop had full-size F keys and a numpad as well).
As mentioned above, there’s no controller, but for anyone who likes this type of switch, there is a diode with each switch, so if you add a Teensy and a case, it should be NKRO. Personally I’m not a huge fan of the switches. They’re linear, but not as nice as the plate-mounted green/yellow Alps switches.
