This is the rare IBM P70 Alps keyboard. If I didn't already have one, I'd be all over it. It has Alps beam springs!

The same Alps switches as in the Japanese IBM 5576-001 and 5576-002 keyboards, but in an ANSI layout, making it the only ANSI keyboard with these switches (unless others surface).

Has a special connector, so you can't connect it to your computer without work.

Here's what mine looks like:

What's the feel like?

Great feel. Like a Cherry MX Blue without any of the problems of that switch. Silky smooth yet sharp tactile point, typical beam spring click.
