The SVGA "monochrome" 9-inch monitor I have was grayscale, by virtue of sending all three color signals to one pin on its little AB. And its curvature fit the Classic II bezel curve-for-curve bolt-for-bolt; perfect. I never took the yoke off, but someone (probably techknight) assured me the pins would match up. Now that I'll have a replacement maybe I'll check the neck-pins and possibly swap it with the burnt-in one in my latest SE/30
