I recently got a keyboard dug up from the 1990s. It's an ICL 16022/032 according to the stamp on the back of the keyboard. As far as I'm able to see it's a spring on top of membrane keyboard. Does anyone have more experience with it?

As far as I know its something between "true" mech keyboards and shitty membrane ones.
Any experience would be much appreciated!
