So my coworker, knowing my fetish with "old keyboards" brought me this keyboard today. It feel similar to a rubber dome, but it does have rubber dampeners so the feel might just be because of that. It obviously has blue sliders, but I can't tell if there is a rubber membrane of sorts underneath the slider since it's plate mounted and the slider is in a plastic shell. I can't find anything on the internet that really goes into detail at all, so I was hoping you guys could give me some insight as to weather this is mechanical, or just a RD with sliders.
