Atari 800

The image is clickable

1979.

Atari 800, and the little sister Atari 400 (yes indeed, for it is said that its working-name was Colleen and Candy after two secretaries of the company), was introduced already in 1978. Due to various problems Atari began ship them 1979. It immediately turned out that it was worth the wait. The personal computer era was just in its infancy, and no one had seen such a capacity previously. When others showed monochrome, or at most 8-colours, Atari proudly showed no less than 128 colours. When others produced a beep, or one or two channels audio, Atari proudly presented 4 channels.

A small feature was that BASIC was built into ROM. It was loaded in through a cartridge during a hatch on top. Moreover BASIC was not written by Microsoft, which was fairly unusual. If you open that gap further, you could reach RAM and increase it up to 48 KB.

In the front you can see four sockets for the joystick. These were later used to plug in additional functionality such as modem or real time clock.

Is there any errors? e-mail and correct me!
