The system played Tennis (2 or 4 players), Hockey (2 or 4 players) and Robot (1 or 2 players against machine).
Tennis was the usual PONG variant. The 4-player mode split the screen horizontally in two parts so that two groups of two players could play at the same time. This was a unique feature.
Hockey did not split the screen when used in 4-player mode, so the game consisted of two teams of one or two players.
Robot is the most uncommon PONG variant. The game is played against the machine by one or two players. The goal is to make the ball go in the hole located on the machine's side. To avoid this, the machine moves up and down a larger paddle to bounce the ball back to the player's side.
[Model FD-3000W]
About 50 CMOS chips were used by the system in addition to the other discrete components (capacitors, etc).
This system had on-screen scoring. Because digital on-screen scoring required more expensive components, the cheaper "follow-me" scoring method was used and consisted of two segments shifting from left to right as far as players marked points.
As with the other systems of that era, the game speed was variable. Here again, FD-3000W used a unique feature: each team had its own ball speed. When the ball bounced on a team, the ball speed was set to the team's speed. This required the use of two knobs (one per team). Two other knobs were used to adjust the picture height and width. This feature allowed displaying a 60Hz signal on some 50Hz monitors, since US systems used a 60Hz frame rate.
The system is quite big due to the large circuit board: around 16.7 inches large (40cm). It did not use batteries: only an AC adaptor powered it.
