Atari introduced the 2600 in 1976. Over 24 years later, it is still going strong; kept alive by classic gaming enthusiasts everywhere. It is powered by a 6507 processor (which is a 6502 without interrupts or the higher address lines bonded out), a 6532 RAM/IO/Timer chip, and the TIA or television interface adaptor. The 2600 was designed with only 128 bytes of RAM and up to 4K bytes of cartridge ROM space. However, in the later years of the console's life, these were gotten around by clever hardware hacks.
