The Intervision 2001 is one of the many systems "software-compatible" with the Arcadia 2001 or the MPT-03 systems to name a few.
Though, the Emerson Arcadia 2001 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.
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 is what is the Intervision 2001. This console group includes : the Emerson Arcadia 2001, Advision Home-Arcade, MPT-03 systems, M1800 systems, Tele-Fever, etc.
All these systems (based on the 2650 & 2637 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 Intervision 2001 was marketed at least in Finland and Switzerland. It's very similar to the Sheen Home Video Centre 2001 (Australia) and the Ormatu Video Spelcomputer 2001 (Netherlands). These two use the same plastic case and have M1800 motherboards.
The Intervision 2001 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.
The Intervision 2001 was followed by an Intervision 3001 model which look similar in every points. Maybe there is a difference on the motherboard. Can anyone confirm this ?
