 In 2006 Atari consultant and historian Curt Vendel, who designed the Atari Flashback for Atari, Inc. in 2004, claimed that Atari released the 8-bit chipset into the public domain.There is agreement in the community that Atari authorized the distribution of the Atari 800's ROM with the Xformer 2.5 emulator, which makes the ROM legally available today as freeware.The Atari machines consist of a 6502 as the main processor, a combination of ANTIC and GTIA chips to provide graphics, and the POKEY chip to handle sound and serial input/output.
