The Atari 400 was the little brother of the Atari 800. Made by Atari, the 400 was noted for having a membrane keyboard, and a single ROM cartridge slot to keep costs down. The Atari 400 & 800 both initially shipped with 8KB of RAM, however, as RAM prices dropped Atari started to ship machines with more main memory. It's worth noting that unlike Commodore's Vic20, the Atari 400 could have its RAM upgraded.
Similar to the Amiga, the Atari 400 had 3 co-processors, the ANTIC, CTIA/GTIA, and POKEY. And just like the Amiga they were designed by Jay Miner.
From an Atari advertisement, 1982:
