That's an interesting point. I've heard this in the past when the MZ first came out. However, I don't remember if it was ever truly (carved in stone) that Technics was primarily responsible for this board. It does look like a Technics board. My main question would be--was Technics responsible for the (sounds) of the MZ-2000? The MZ's sounds were good and way above the tradition Casio, but coming from Technics I would have expected a little more. The KN series was a great sounding line up. Maybe Technics had a hand in the overall design and operating system for the MZ-2000.
