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.
