It has linear NMB Hi-Tek "space invader" switches which, in my opinion, feel rather similar to Cherry MX blacks. They are a pain to clean because the slider (space invader face) comes off with the key cap and putting this back on the base can be fiddly. Surprisingly, there aren't any stabilizers underneath the larger keys except for the space bar.
The legends look dye-subbed and the caps feel like PBT, not sure though.
The board doesn't seem to work on modern day PCs, although it comes with an AT DIN plug (5 connectors in a 180 degree arc); not via a DIN->PS/2 adapter nor with a DIN->PS/2->USB adapter chain. The LEDs light on shortly so the power should be ok. I haven't tried Soarer's converter yet, though.
DT user maxrunner apparently had a NIB one: http://deskthority.net/marketplace-f11/ ... tml#p89822
