Atari 65XE

Introduced at the 1985 CES in Las Vegas. The Atari 65XE was the direct replacement for the Atari 800XL Personal Computer. Price at $99.99 the 65XE was 100% compatible with all of the Atari 400/800, and XL software (some programs required the use of a "Translator" disk before use) and all peripherals. The 65XE computer had 64K of memory like the Atari 800XL and all of the same custom chips as well. One additional chip was added into the XE series computers which was called the FREDDIE chip. This was a MMU chip (Memory Management Unit) allowing the system to handle memory swapping and larger amounts of memory more efficiently.
