there was a listing on kijiji (where you can buy used stuff) although you could also check other sites like Ebay.

This keyboard is now about 35 years old according to the manufacture date. The older ones only exist in PS/2 (in fact, these were the original PS/2 keyboards) so you might want to get an (active) adapter if your motherboard doesn't have PS/2 ports.

Cool asf, how'd you get it :?

IBM Model M

What keyboard is that?
