:: Introduced in May of 1984, the 7800 ProSystem came out fighting with a series of well-engineered accessories and peripherals developed in tandem by parent company Atari. This series of accessories, known as the "ProLine" series of accessories, was introduced not only to help bolster support Atari's new flagship video game system, but also to push the performance and enjoyment quality of the 2600 to new limits. The new advanced series of Atari accessories were engineered to all be fully compatible with the 7800 ProSystem, and recieved the name "ProLine" in keeping with the "ProSystem" name motif of the new Atari 7800.

While ultimately the 7800 ProSystem severely lacked the third-party support that it needed to become a world-wide success, the 7800 ProLine accessories are all interesting and well-thought-out, each in their own right. These accessories are detailed below. ::

	INTRODUCED: MAY 1984; JUNE 1986 DEVELOPER: ATARI / GCC MODEL NUMBER: CX7800 The Atari 7800 ProSystem was first introduced in 1984 (and again later in 1986 under new ownership) to compete with the ColecoVision and Intellivision systems, however it soon found its self facing newcomers from Nintendo and Sega. The 7800 ProSystem featured an 8-Bit Processor and an advanced graphics chip, code-named "Maria" which provided graphics that rivaled those of the local arcade at the time of its release. The 7800 is also backwards-compatible with all existing 2600 technology. Packaged with the 7800 were two ProLine Joysticks, a/c adapter, television connections, instructions, and the cartridge "Pole Position II". The exterior is handsome and refined, its graphics were state of the art, but inside it has the soul of a 2600. The 7800 is the culmination of everything Atari stood for, combining arcade quality graphics with the extensive library of 2600 games and accessories. The 7800 lost complete support from Atari in 1992 after an 8-year ride. The 7800 still holds a small but dedicated following to this day.

	INTRODUCED: MAY 1984 DEVELOPER: ATARI MODEL NUMBER: CX24 Packaged with the Atari 7800 ProSystem were two Atari 7800 CX-24 Joysticks. The CX-24, better known as the "ProLine Joystick", was designed and released in 1984 as the answer to many gamer's complaints. The classic 2600 Joystick was a solid winner of a controller, however it was outdated and overrated. Atari gamers were severely let down with the 5200 joystick design with clumsy unresponsive control. Atari shot back with a controller that was engineered to be more advanced and responsive than the original 2600 joystick, and would work with all 2600, 7800, and 8-Bit Computer systems. The CX-24 Pro-Line Joystick features dual fire buttons, responsive control, and a sleek easy to hold design.

	INTRODUCED: MAY 1984; JUNE 1986 DEVELOPER: ATARI MODEL NUMBER: CX78xx The Atari 7800 ProSystem game cartridge was a real feat of electronic engineering for its time. One primary objective of the 7800's development was to create a system that would be out-of-the-box reverse compatible with all of the existing 2600 technology, not having to rely on special adapters and software to make this possible. This dictated that the 7800 cartridges would have to be the same size as the original 2600 cartridges. The 7800 cartridges generally held around 8K of memory, however a 32K "Super Cartridge" was developed which allowed more complex "Super Games" to be played on the 7800. Games such as Ballblazer, Impossible Mission, and Karateka were developed to take advantage of this almost "unlimited" memory for the 7800. The "Pole Position II" game cartridge was included with the Atari 7800 ProSystem.

	INTRODUCED: OCTOBER 1987 DEVELOPER: ATARI MODEL NUMBER: CX78 Atari decided early on that one key feature of the 7800 was to be its sleek and refined joystick. Atari engineers had laughed at the Nintendo controllers. "How do you play video games without a joystick?" they asked. But things soon changed as joypads became mainstream and Atari was forced to compete. In 1987 Atari introduced the CX78 Joypad to the European market. The CX78, better known as the "ProLine Joypad" featured precise control, comfortable design, dual fire buttons and a unique directional pad which had a thumb-stick that could screw in and out of the pad. You could use the joypad just like the NES controller, or you could choose to screw in the peg and play with a small thumb-sized joystick. The ProLine Joypad was not introduced to the American market until independent Atari dealers imported the Joypads in the late 1990's.

	INTRODUCED: MAY 1987 DEVELOPER: ATARI The Atari Light Gun was introduced in 1987 along with the Atari XE Game System, for use with all 2600, 7800, and XE Series Systems and Computers. The Atari Light Gun is needed to play 7800 titles such as Meltdown, Barnyard Blaster, and Sentinel. These games were in direct response to the series of light gun games from Nintendo and Sega such as Duck Hunt and Jungle Hunt. The Atari Light Gun features the exclusive XE-Series styling, and is the only peripheral for the 7800 marketed by Atari which is not Atari Black.

	INTRODUCED: MAY 2000 DEVELOPER: ATARI / GCC / GARY RUBIO MODEL NUMBER: CX78HSC The High Score Cartridge is a unique device that sits firmly between the 7800 and a compatible 7800 game cartridge, of your choice. This device allows you to save your high scores on particular 7800 titles. When General Computer Corporation (GCC) became involved with the development of the Atari 7800, they teamed up with the Atari development staff to work on a few innovative accessories which were to make the 7800 a truly impressive system. The first of these accessories was the Atari 7800 High Score Cartridge. However, when Jack Tramiel bought Atari in 1984, he ultimately pulled the plug on all 7800 accessories that were still in development. In 2000 High Score Cartridge programmer Gary Rubio and AHS founder Curt Vendel teamed up to make this cartridge a reality. Pictured to the left is the version of the High Score Cartridge which was sold by Atari 7800.com from 2000 - 2002, featuring a fully enclosed cartridge (top and bottom) and a premium-grade label.
