Palcom PX-7

This is a very particular MSX 1 computer ! It has an enhanced feature : as the Sony SMC 70, it has an interface (Laser Vision) to control a videodisc player and to do genlocking (superimposing pictures and texts above the Laser Disc image). It was mainly used for video production/editing.

The european PX-7 was black whereas the japanese version was black and silver.

A graphic tablet (PX-TB7) was also sold with the Palcom PX-7. With this thing you could create illustrations, shapes and various backgrounds, then store up to 8 of these shapes with their respective animation programmes into the computer memory.

The LD-700 Laser Disc Player was also sold as an option. When linked to the Palcom PX-7, the computer could entirely control it and exchange information.

Pionner also sold the ER-101 interface (Laser Vision) unit which made it possible for all MSX computers to have the same functionalities as the Palcom PX-7.

Please consider donating your old computer / videogame system to or one of our partners from anywhere in the world (Europe, America, Asia, etc.).


Miroslave Werner, no need to post image of your own piece, we arent interested.
