@amoroso @weekend_editor I wonder, when did main color screens appear? In ancient times it was typical (on a Symbolics) that it could have an additional color board, but that was not a screen for the usual applications (listener, ...), but a color screen dedicated for displaying/drawing in color. I think the capability to run the main console on a native color screen appeared late, for example because drawing on a color screen was slow or because the system was hosted.
