History and Trivia


Released in Europe during 1983, the G7400 was the next generation console for Philips. It featured the basic components of a Philips Videopac, plus a new graphic chipset, the "Plus". Philips intended to sell the new hardware for at least a couple of years, with plans for more than fifty Videopac cartridges. Due to the collapse of computer/console market in 1984, however, this promising console never took a great hold on the market, and the fifty cartridges quickly became four.

It seems there was also a plan to release this system in the United States with the name "Odyssey 3", under the Magnavox label, but it seems that no unit ever reached the market.

The first Videopac game to take advantage of the enhanced capabilities of the G7400 was "Terrahawks" (Videopac 51). Also some older Videopac cartridges such as "Race", "Stonesling", "Satellite Attack", "Freedom Fighters" and "Pickaxe Pete", were re-released for the upgraded console. In the majority of cases, these games were made backwards compatible with the old G7000 and, due to the limited space available on the carts, the enhancements reduced to addition of colourful backgrounds.

Four carts only were produced with exclusive support for the G7400: "Helicopter Rescue", "Norseman" and "Trans American Rally" and the "Microsoft Basic Expansion Module".

There exist various variations of the G7400: the Jopac JO7400, the Schneider G74+ and the Radiola Jet 741.
