Bueno pues aprovechando que he visto este anuncio he decidido sacar a la luz el P2000. no he visto ningun post...
No hagais caso de la publicidad es un mamotreto de mucho cuidado, no es pesado pero si voluminoso.... y lo de economico... pues lo mismo para una empresa si... para un particular pues no mucho....
"Solo" costaba 290.000 Pesetas en 1982 (1747 Euros y direis pues no es tanto con los ojos de hoy... pero... con IPC a dia de hoy equivaldria a 8.535,78 Euros)

"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".
Por lo que he encontrado la principal diferencia es el video...

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:
00 Unused 10 Unused
01 Alpha Red 11 Graphics Red
02 Alpha Green 12 Graphics Green
03 Alpha Yellow 13 Graphics Yellow
04 Alpha Blue 14 Graphics Blue
