abc80.v: make it possible to simulate a green or yellow screen
Make it possible to make the display green or yellow (should really be amber). Switches changed: SW[4] - suppress red (used for green) SW[3] - suppress blue (used for green or amber) SW[2] - V.24 instead of printer for serial port Add a new file to list the current LED/key/switch assignments.
