This video controller supports two modes, 640x480 1bpp (B&W) and 320x240 4bpp (16 colours). The idea is to have it connected to the Z80 board as a terminal by default, but when a port is written to, or maybe even if a command is sent, it interprets commands for graphics primitives. This should make it easy to implement graphics commands in existing BASIC software with simple Print statements. The board will also handle a PS/2 keyboard interface.
