Does anybody know if the IBM 4704 Bank Terminal Keyboard is buckling spring?
Here's a picture of it:

It's quite possibly beam spring, even more arcane... Haven't found much about it online, but here's an abbreviated IBM chronology that mentions it being new in 1981.

Check out the beam spring page at the Deskthority wiki.

I hadn't even considered that it might be beam spring!
I like the 50 key grid format. I may just risk it and buy it: just to see what it is...

It's way too low profile to be a beam spring. Must be Buckling Spring or some rubber dome.
