Zusammenfassung:	In a pixel display system, a plug-to-plug compatible pixel decoder palette is provided which is responsive to a predetermined sequence of commands on an I/O data channel to switch the mode of operation of the pixel decoder palette. The pixel coder palette comprises a random access memory used as a look-up table to store colors to be displayed and the I/O channel is used to store new colors in or read colors out from the random access memory. The different modes of operation of the pixel decoder palette involve operating on intensity values represented by 6-bit bytes and 8-bit bytes and involve continuous edge graphics wherein pixels bridging boundaries between objects are displayed as mixes of the colors on each side of the boundary.
