Philips P2000

From Wikipedia, the free encyclopedia

The Philips P2000T home computer was Philips' first real entry in the home computer market, after the Philips Videopac G7000 game system (better known in the U.S. as the Magnavox Odyssey2) which they already sold to compete with the Atari 2600 and similar game systems.

Basically the P2000T was a Z80 based home computer that used a Teletext display chip to produce the video picture and a small Dictaphone cassette recorder for mass storage. It seems that Philips used components they already produced for other markets (Televisions and Dictaphones) to quickly design a small computer system. It was partially designed by Austrian professor Dieter Hammer.

They also copied the ROM cartridge system from their Videopac G7000 game system. One of these cartridges contained Microsoft BASIC. It was also possible to use cassette tape floppys.

Although the Teletext video chip permitted a quick entry into the home computer market, it was also the major weakness of the P2000T. Using the Teletext standard in itself was not a bad idea because it did support eight colors and rudimentary graphics. But unlike later entries in the home computer market which also supported a Teletext display mode, such as the venerable BBC computer and the Oric Atmos, the P2000T did not support a high resolution display mode. This made it very difficult to develop interesting games for it.

As a result, the P2000T had only a limited success, and Philips later replaced it with their MSX machines. The machine did gain popularity in The Netherlands, especially in the realms of science, education, and data communications (videotex).

The Philips P2000M incorporated 2 5.25-inch floppy disk drives beside 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 in the way it handled display of special characters (color, "graphics mode"), which made most P2000T games unplayable.

The P2000T was produced in Austria.
