Atari 400 PAL

The Atari 8-bit family is a series of 8-bit home computers introduced by Atari, Inc. in 1979 and manufactured until 1992. All are based on the MOS Technology 6502 CPU running at 1.79 MHz, roughly twice that of similar designs, and were the first home computers designed with custom co-processor chips. This architecture allowed the Atari designs to offer graphics and sound capabilities that were more advanced than contemporary machines like the Apple II or Commodore PET, and gaming on the platform was a major draw – Star Raiders is widely considered the platform’s killer app. Machines with similar performance would not appear until the BBC Micro in late 1981 and the Commodore 64 in 1982.

The original Atari 400 and 800 models were released with a series of plug-n-play peripherals that used Atari’s unique “SIO” serial bus system. Over the following decade several versions of the same basic design were released, including the XL and XE series of computers and matching peripherals. All of these used the same basic logical design, with various changes to the physical layout to lower production costs as chipmaking and manufacturing processes improved over time. The early machines were expensive to build, but dependable. Later models like the XEs were greatly cost-reduced and generally not as robust. Sub-models of these later designs were sold into the eastern European market after sales of the main lineup had ended.

Overall, the Atari 8-bit computer line was a commercial success, selling two million units during its major production run between late 1979 and mid-1985, putting its sales on par with machines like the Sinclair ZX Spectrum and TI-99/4A. Its primary competition in the worldwide market was the Commodore 64, by far the best selling computer of the 8-bit era. Atari also found a strong market in Eastern Europe and had something of a renaissance in the early 1990s as these countries joined a uniting Europe. Some estimates place sales during this period at another two million units.

Atari 825 – 80 Column printer:

Atari 825 - 80 Column Printer

Atari introduced with its Atari 400 and 800 series computers its first 80 Column printer.   The Atari 825 which actually a repackaged Centronics 737 printer.   Earlier models had limited capabilities, the later 825 models with the extended basic character set had the capability of producing the Atari ATASCII graphics character set.  The Atari 825 required the use of the Atari 850 interface module to allow it to communicate with the Atari 400 and 800 computer because it had a Centronic parallel interface on it instead of the Atari SIO interface which the Atari 820 and Atari 822 printers had built in.
