First Dimension entered the US video game market in 1975. Located in Lewis Street in Nashville TN, this small business released a few systems. Their catalog listed six models, of which only two are known to exist. Their first system was called Video Sports, model FD-3000W, and came out in late 1975. It played quite advanced PONG variations for the era. However, problems appeared while this system was being produced and killed the business little by little. This explains why later modes are not well known. The only other model known to exist is model 76 made in 1976.

In addition to the press article below, Bart Bailey who used to troubleshoot faulty FD-3000W systems remembers how bad the business was:

Bad Management:
The boards were initially stuffed manually by semiliterate southern women working at minimum wage.
There were numerous problems with insertion polarity, color code mistakes and missing and wrong (chip) components.
The wave soldering machine operators had little training and even less knowledge of flux state vs temperature.
They created entire batches of boards with solder bridge errors, along with many trichloroethylene spills that would cause them to leave the room temporarily with the machine running unmonitored.

There was a primary tech area whose main function was to supply missing components, replace reversed polarity diodes and chips, and sometimes devote an entire shift to de-soldering or cutting out solder bridges.
The second level where I worked was dedicated to troubleshooting the logic paths (usually blown gates), or the RF modulator ramp oscillator (was somewhat unstable).

This gross inefficiency caused the company to lose some critical orders during the xmas season 1975 and subsequently default on some payments to part suppliers. It was about this time that they had leveraged some of the company's assets to purchase three automated board stuffing machines.
This improved the "dropout rate" significantly, however the die was cast, and no amount of efficiency improvements could salvage the lost reputation, much less catch the stiff competition from a much better managed Atari.

As the company was drawing its last breaths, there was a consortium of politicians and investment swindlers fronted by the well known John Jay Hooker who managed to milk out the last drops of solvency, until total bankruptcy was declared in late 1976.

Note: near the end there were several occasions that our paychecks would bounce, and several of the more motivated employees started carrying guns to work. Eventually all employees were laid off and the company's remaining physical assets were liquidated to private parties.

Although FD-3000W suffered that bad business, it played very uncommon games and used "analog logic" (CMOS gates in analog mode). Technically talking, it had the big advantage of using a composite output, allowing to plug the game to a computer monitor for a crystal clear picture. An RF switch-box was provided for use with a normal TV set. It modulated the composite video signal, so did not provide the best quality pictures. As a matter of fact, the signal was first modulated by the RF switchbox in order to be used by the TV set, and then demodulated by the TV set, hence a loss in quality. The composite output was a unique feature as of 1975 and allowed playing this game with crystal clear pictures on any computer monitor or TV set equiped with a composite input.

The system was designed in 1975, so could only use CMOS or TTL logic gates. About 50 CMOS chips were used by the system in addition to the other discrete components (capacitors, etc). The games were also different from most others of the same period: 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 in 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 players side.

Yet early, 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. As of early 1976, nearly 50,000 units were produced. The total amount of units manufactured is unknown, though the highest serial reported is 33235 (our specimen). Several revisions were made to the circuit board, ranging from A to G or even higher.

Two boxes were made for this game. The initial one was black with color logos. Later in 1976, a cheaper box was made with a black and white xerox-like paper sticked on the carton box. One of our specimens was found in unused condition: the original container box is still sealed. We do not know what type of box is inside, although it is believed to be the second one. It is also possible that the black and white covers of the container boxes were used for the later, cheaper boxes. Ah, rumors without facts...

A rare example of quick fix in the production line of the above board:
a replacement chip was piggy backed over the dead one (left), and
another chip was solded in reverse position, hence the brownish solders.

The Rev. G board pictured above did not pass the final tests and
was sent back to the production line. The reason was either a 4011 chip
soldered in reverse, or a bad or wrong chip. The chip was replaced,
hence the brownish solders as pictured. This specimen was sent back
on March 12, 1976, and accepted the day after.

Also, some solders between the highlighted capacitor
and resistor shorted together and were cleaned.
