Twenty-seven cartridges, termed 'Videocarts', were officially released to consumers in the United States during the ownership of Fairchild and Zircon, the first twenty-one of which were released by Fairchild. Several of these cartridges were capable of playing more than one game and were typically priced at $19.95. The Videocarts were yellow and approximately the size and overall texture of an 8 track cartridge. They usually featured colorful label artwork. The earlier artwork was created by nationally known artist Tom Kamifuji and art directed by Nick Talesfore. The console contained two built-in games, Tennis and Hockey, which were both advanced Pong clones. In Hockey the reflecting bar could be changed to diagonals by twisting the controller, and could move all over the playing field. Tennis was much like the original Pong.
A sales brochure from 1978 listed 'Keyboard Videocarts' for sale. The three shown were K-1 Casino Poker, K-2 Space Odyssey, and K-3 Pro-Football. These were intended to use the Keyboard accessory. All further brochures, released after Zircon took over Fairchild, never listed this accessory nor anything called a Keyboard Videocart.
There was one additional cartridge released numbered Videocart-51 and simply titled 'Demo 1'. This Videocart was shown in a single sales brochure released shortly after Zircon acquired the company. It was never listed for sale after this single brochure which was used for winter of 1979.
It is amazing that we got all these games in their original packaging and they feel almost like new :)
