These are very high quality and completely worth the price. They ping loudly though!

You have two options to use on PC. The first (what I did) is to replace the microcontroller with a teensy. The second (more recently developed) is to convert the protocol (these are apparently the same as the 4704 keyboard protocol and use the same cable). Thanks to soarer and Hasu for this.

I recently picked up a wang 725-5971 with salmon alps and I really dig the feel and sound of alps switches.  I can't wait to try these vintage tee mount alps.

Thanks for the info  Dorkvader,  I'll probably use the same method you did and go with the teensy.  Also, thanks to Soarer and Hasu for enabling us to use these keyboards.

Thank you for the heads up on these boards! Picked one up to see what all the fuss is about. And I think that it's a beautiful looking board too.

I know this thread is a bit old, but you wouldn't by chance have a guide showing how to replace the microcontroller with a teensy? I recently picked one up and would like to give it a go, though I have zero experience with it.

Are these just standard Alps stems?

Nope, tee mount.
