The PCT-55 is an improved version of the Paxon PCT-50, as it comes with more RAM, an external RGB input and a video composite output. Some bugs have been fixed and the unit is a little less heavy.

It was released by the Japanese company General and was available only in silver. The MSX computers produced by General are called 'Paxon'. PCT means 'Paxon Computer TV'.

This machine has only one cartridge slot, the keyboard (PCK-50) is optional. The MSX is internally connected to the monitor via a "high quality" RGB interface. This was appreciated by the Japanese users who wanted to make quality screendumps of their favorite games.

The official price is ¥138,000 for the main unit, ¥3,500 for a joystick (PCJ-50) and ¥18,500 for the keyboard.
