"The P2000M incorporated two 5¼-inch floppy disk drives,[7] besides a built-in monochrome screen. It could run CP/M or Microsoft BASIC applications, depending on the cartridge used. It was incompatible with the P2000T due to the way it handled display of special characters (color, "graphics mode"), which made most P2000T games unplayable".

Video processor
The video processor used in the T-model is the SAA5050 teletext character generator. In some versions, it is replaced with a variant with a different character set (e.g. SAA5051 has a German character set). It generates 96 alphanumeric and 64 graphics characters. In addition, there are 32 control characters which determine the nature of display. It's basic input is the 7-bit character data from the teletext page memory. Following are the control codes supported by this device:
