In the 1990s, I worked on a Canon typewriter (AP800) that had a similar-looking keyboard. That keyboard is the best I've ever had the pleasure to type on and I've tried quite a lot, including IBM Models M and F, all Cherry colors, Topre, etc. I could type for hours on that thing and not get tired. I would love to get my hands on a Cat to see if the keyboard is as good as that one was.
