The Enterprex Apollo 2001 is a pong-style game console with four games running on the AY-3-8500 Ball and Paddle chipset. The players used two sliders on the console to control the game, and the console had switches for ball speed, serve, ball angle, bat size and automatic serve.

This device was produced for the German market as the "Universum TV Spiel".

The AY-3-8500 "Ball & Paddle" integrated circuit was the first in a series of ICs from General Instrument designed for the consumer video game market.

In 1975 General Instruments developed the AY-3-8500 chip that would revolutionize home gaming. Initially there was no interest in the chip, General Instruments could not find interested buyers. At the same time Coleco had the desire to built a home console. Thanks to Ralph Baer, the brain behind the Magnavox Odyssey, Coleco and GI found each other and in 1976 Coleco Telstar was put on the market. It immediately became serious competition for the Magnavox Odyssey.

Ultimately the AY-3-8500 was used in more than 200 consoles, from the APF TV Fun, the Philips Tele-Spiel Las Vegas, the Sears Hockey Tennis game to the Tandy TV-Scoreboard and many, many more.

The AY-3-8500 was designed to output video to an RF modulator, which would then display the game on a domestic television set. The AY-3-8500 contained six built in games:

1. Tennis/Pong
2. Soccer/Hockey
3. Squash
4. Practice game
5. Shooting 1
6. Shooting 2

The AY-3-8500 was the 625-line PAL version and the AY-3-8500-1 was the 525-line NTSC version. It was introduced in 1976 with Coleco the first manufacturer to implement the chip in its Telstar console. Only a few external components were needed to build a complete system, which made this chip an attractive option to produce cheap pong machines.

The AY-3-8500 was the first iteration of the chip with black-and-white video output. It was possible to colorize the game by using an additional chip, such as the AY-3-8515.
