CTRL/W B White on Black, 8x10 characters, Charset 2
CTRL/W C Black on White, 8x10 characters, Charset 2

Attribute On is set with Shift/Arrow Up and reset with Shift/Escape

Attribute Off:                 Unshifted As Key tops (lower case)
                               Shifted As Key tops (upper case)
                               with Graphics characters 129-158
