Atari
800

The Atari 400 and 800 were the first home computers to use custom coprocessors and the first to use "sprites" and special video interruptions like display lists; features that would be implemented later on the Commodore 64, then on the Commodore Amiga (Atari 400/800 and Amiga were both designed by Jay Miner).

It offered high graphic resolution, lots of colors and great sound capabilities, more than other computers could do then! The two models had same characteristics, but the 800 had 48 KB of RAM (instead of 16 kb), two cartridge ports (only one for the 400) and a proper mechanical keyboard (a membrane keyboard for the 400).

In fact the very first Atari 800 Computers were shipped with 8 or 16 KB memory, expandable to 48 KB. After initial release, the 800 came standard with 48 KB memory.

Prior to production, the 800 was known inside Atari as code name "Colleen". It is rumored that Colleen and Candy (the 400 code name) were actually secretaries at Atari.

Here is a work in progress of a game/demo which shows that the
Atari 400/800 etc (48k) computers are still a wonderful computer system
that can completely dazzle and charm people today,
even though it may be 30 odd years later on...

Here is the actual demo you can download and run:

Here is a video of the game demo running...

Just played MULE last night. I love my old Atari 800, it makes a great conversation piece for visitors. The more games you have the more memories you share.
