Console: Atari 5200
In the early 1980’s Atari was still successful with their Atari 2600 console, but soon there were many competitors including Mattel’s Intellivision (released 1979) that were taking some of the gaming marketshare away from Atari. Atari had also a fairly successful line of Atari 400 and Atari 800 8-bit computers at the time, and in the late 1970’s Atari decided to take the same chipset used in their 8-bit computers, and create a stand alone home console. At first the system was called the “Atari Video System X-Advanced Video Computer System”, and the project was code-named “Pam” after a female employee at the time with Atari Inc. Some people speculated that Pam also meant “Personal Arcade Machine” because many of the games for the system were direct ports from the arcade. There are some 100% working “Atari Video System X” models floating around today, but they are extremely rare.
Things that set the Atari 5200 apart were that it featured four controller ports, where every system up to this point only had two. It also featured a TV switch-box which would enable the system to automatically switch to the game signal when the system was turned on. Previously people had to manually switch the RF box between TV and the game signals. The downfall of this unique RF box was that the power adapter had to be plugged into the RF box, which is very similar to the RCA Studio II and how that powered up.
In 1983 Atari redesigned the Atari 5200 to only include two controller ports and replaced the power supply to the more conventional way, and got rid of the auto-switching RF box.
Unlike the 8-bit line of Atari computers, the Atari 5200 did not include a keyboard, didn’t have an 10KB operation system but rather a simple 2KB BIOS, and non of the Atari 400/800 computer games are compatible for the Atari 5200 and vice versa.
The Atari 5200 controllers had a lot of great inovations, but unfortunately they aren’t reliable, and one big reason the system didn’t sell well. The controllers featured an analog joysticks that could move in all different directions, a pause button on the controller (very unique in this time), start button, reset button, numeric keypad, and four action buttons on the side. The Achille’s heel for the controllers was that the analog joysticks featured a week rubber boot rather than metal springs, and many of the joysticks ended up not being very responsive, and thus unusable.
Atari also released a Pro-Line Trak-Ball controller for the Atari 5200 to be used for games including Centipede or Missile Command.
Soon after the Atari 5200 hit the market Coleco released their Colecovision system in the market as well. Ultimately the Atari 5200 didn’t fare well because Atari was still focusing primarily at their already saturated Atari 2600 console. Atari had plans on releasing a much smaller version of the Atari 5200 called the (Atari 5100 or “Atari 5200 Jr.”), but that never saw the light of day outside of a few rare prototypes. In 1984, only a few years after the initial release, Atari dropped all support for the Atari 5200.
In total only 69 official Atari 5200 games were released. There is still however a homebrew market out there for the system. The games were significantly larger than all of the other types of games in the market, and there is no sticker game label at the top of the game to tell which game it is when they games are stacked. Most of the games released for the Atari 5200 were arcade ports.
