In 1982, Atari revealed the Atari 5200 SuperSystem to the gaming public. Based on the Atari 400 8-bit computer, the 5200 was Atari's answer to the competition it was receiving in the videogame market. Knowing that its 8-bit line of computers already had an excellent game library, Atari decided instead to transform its 8-bit computer into a powerful game system. In most respects, the 5200 was very similar to the Atari 400 computer, but it featured a sleek, wedge-shaped case with only a single power button on the unit itself. The most noticeable change from the Atari 8-bit line was the inclusion of two analog joysticks. These new controllers allowed for a full 360degree movement, but unfortunately they were not self-centering and proved awkward to use with many games. The controllers were highly prone to failure and became the primary bane of the system. In addition to the analog control stick, the 5200 controllers also featured two independent fire buttons, a numeric keypad, and Start, Reset, and Pause buttons built on the controller. Atari 8-bit computers and Atari 5200 SuperSystem have been around for over 20 years now, and in that time many hacks have been developed to enhance these systems. A large “homebrew” community is developing new software for the systems, keeping the spirit alive for Atari fans. This chapter describes how to perform the Atari 8-bit and 5200 hacks. Some of these hacks include adding a Blue Power light-emitting diode (LED) to the Atari 5200, creating an Atari 5200 Paddle, and building Atari 8-Bit S-Video and Composite Cables.
