Are there any photos online of CXG Sphinx Legend that show the button panel? Or does someone here have a photo they can share?
Not the one on spacious mind's site, that picture is small, and not the mockup/prototype in the 1992 brochure. And not Legend II either.

edit: found one, and it has what I wanted to see: the position of the lines and their colors.
