The Vidéo Ordinateur MPT-05 is one of the many systems "software-compatible" with the Interton VC-4000 or the Radofin 1292 to name a few.
Though, the Interton VC-4000 is the maybe most popular system of this console group, it was not necessarily at the origin of it. Things must be seen differently. Philips / Signetics developped a hardware platform to demonstrate the possibilities of their Signetics 2650 & 2636 chipsets. Somehow, this hardware was licenced to many third-companies around the world resulting in systems like the Interton VC-4000, Voltmace DataBase, Acetronic MPU-1000, Radofin 1292, etc.
Most electronic boards of these systems were build in Asia by companies such as Radofin or Soundic. The codename "MPT" was also used by other system families: MPT-02 products are RCA Studio II compatible systems, MPT-03 are "Emerson Arcadia 2001 compatible" systems and MPT-04 and MPT-05 are "Interton VC-4000 compatible" systems.
Some times later, the hardware was improved, with the use of a Signetics 2637 instead of the 2636 (handling the audio & video), somehow resulting in a new wave of licenced systems, all based on the same hardware and playing the same games. This console group includes : the Emerson Arcadia 2001, Advision Home-Arcade, Prestige MPT-03, Tele-Fever, etc.
All these systems (based on the 2650 & 2636 chipsets) are "software-compatible" with each others. It means that they all could play each other games if their cartridge slots were identical (which is not the case, resulting in sub-groups).
The Vidéo Ordinateur MPT-05 was marketed in France by ITMC. What is quite strange is that other systems use the exact same plastic case such as the Intervision 2001 and Intervision 3001, or the Sheen Home Video Centre 2001 (Australia) and the Ormatu Video Spelcomputer 2001 (Netherlands), but they are not compatible with the MPT-05! Indeed the ITMC MPT-05 is an "Interton VC-4000 compatible" system (2650/2636 chipsets combo), whereas the other are "Arcadia 2001 compatible" systems (2650/2637 chipsets combo)! What a mess...
The MPT-05 is equiped with two detachable controllers made of a screwable analog joystick and a 14-buttons keypad (rubber buttons). Small plastic layers were delivered with each game, explaining the different key functions when placed over the keypads (like with the Mattel Intellivision).
The Control panel is made of 4 buttons (Start, Clear, Select A and Select B) and the power switch.
