Eh? If you install the color card you get color output on the 
builtin graphic D-sub. And if you remove the color option board
then you get no output from the machine at all (no sync). It may
happen that there is a strap somewhere to select between them, I
don't know about that.

Due to my docs there are 2 types of of color option boards; the 4-plane
VS40X-MA and the 8-plane VS40X-PA. Both of them Dragon-based.
