as direct reaction to the publication Apple - home computer developed and produced to date only the company Atari active in the video game industry its own 6502- CCU - home computer model row was based: the a riser model Atari 400 with transparency keyboard and first only 8 kByte RAM (16 RAM kByte later according to standard) and, the expandable Atari 800 with up to 48kByte RAM, thought for more elevated requirements, and typewriter keyboard. Contrary to Apple the Atari computers were equipped with more efficient and electronic special components which can be programmed more easily (ANTIQUE ONE , CTIA , POKEY) and them contained besides four connections for Joysticks contrary to the models of the competition, which had to be re-tooled only cost-intensively. The Atari 400/800-Heimcomputer was besides the first devices, which had intelligent “binding of the peripheral devices one „- by the so-called. Atari SIO bus, which is not dissimilar to the today's USB.

A well co-ordinated pallet at accessories, plays, application programs, programming languages, excellent customer service, the integration of third offerers and the purposeful placement of the computers in educational facilities contributed considerably to the success of this series of the Erstverkauf in the year 1979 on.

Atari XL

Atari 1200 XL
Atari 800 XL
Atari 600 XL

as answer to the rapidly growing competition in the home computer range in particular by the Commodore 64 and the Spectrum - computer brought 1982 the first model of the XL-series (from the English „eXtended LINE “formed acronym ) to Atari on the market: the Atari 1200XL. This model was taken to the old because of compatibility problems with series immediately again by the market and 1983 by the models 600XL (16kByte RAM) and 800XL (64kByte RAM) replaces.

The electronic architecture of the XL-computers differs only slightly from that the 400/800-Baureihe. Only some changes in the store management ( OS fade outable), improved diagram component named GTIA - before a CITA - (256 possible colors), now ex factory the inserted programming language BASIC and an outward led parallel bus interface (PBI), in order to be able to tie up extensions more efficiently, in addition came. Besides the amount of at the same time connectable Joystick was limited to only two. The XL-computers and their periphery exhibit clearly verschlankte and less playful housings.

The development of the XL-series was resumed until 1984. During this time a set of concept studies and prototypes (computers 1400XL and 1450XL, extension module 1090XL, various floppy stations also for disks in the 3 ½ tariff format, CP/M modules etc.) developed, which by details as electronic language production integrated itself or also for conditions at that time very fast modems distinguished. These and further development projects like the 1650XLD (with 80186 emulation), the 1850XLD “Lorraine” and 900XLA the having a Musiksynthesizer never brought it due to changes in Ataris to development philosophy to ready for the market ones.

Atari XE

Atari 65 XE
Atari XE Game system

in the context of the introduction of the sp series took place 1985 besides a revitalization of the 6502-CPU-basierten product range via the distribution of the XE-models (from the English “eXtended LINE Enhanced” formed acronym), which oriented organization of the housings with a more modern, at the sp series offer could. The technical changes to the XL-series were essentially limited to a further development of the RAM replicated system approach (64kByte with the 65XE and 800XE; 128kByte with the 130XE) and unite changes for the lowering of production costs. The replacement of the parallel bus by a slimmer however not compatible expansion haven, led made thereby, outward, and in particular the installation of qualitatively inferior keyboards made the efficient employment more difficult within the home user range and led to the drift of a large customer group to the sp series or to the competition. The rising costses to the victim also promising projects fell like a portable version of the 65XE as well as one with the Synthesizer Spezialbaustein AMY equipped variant the same, further various peripheral devices as 3 ½ tariff floppy disk drives, monitors and color printers.

Likewise to the product range of the XE-series the Game system (XEGS), expandable by an external keyboard unit to an adequate XE-computer, is to be counted. The XEGS is considered as attempt Ataris to decrease Nintendo NES and SEGAs master system of market shares.

The generally diminishing demand within the range of the 8-bit of computer segment in the USA, bad application of the products in Europe, missing leistungstarke periphery, bad processing and support lacking by third manufacturers in particular within the play range led too in the comparison to the 400/800 and XL-series small sales figures, whereby at that time the Atari 800XE produced for the Eastern Bloc formed an exception. The production of the XE-series was stopped in the year 1989.
