For sale is a vintage NTC KB-6251EA mechanical keyboard. Switches, case, and keycaps have all been cleaned. Plate is in good condition. This one has the OA2 alps clone switches (the type with the wide steel leaf). They remind me of blue alps, but more tactile. (Swapped them with SKCM whites so I can swap those in my 6151 which is much better.) The sound isn't quite up there with genuine alps, but it's still not bad. Many of the keycaps have shine, but being doubleshot they will never wear off.
A few keys have broken stems, but they all sit on the switches no problem. (f7, tilde, backspace, numpad 1, numpad minus.) I will secure those with masking tape for shipping. DIN 5 to ps2 adapter included.
