ATARI  XL/XE

In 1979, Atari introduced the Atari 400 and 800 personal computers, using the 6502 microprocessor. Originally, both the 400 and 800 were sold with 8 KB RAM, but later most 800's were sold with 48 KB and 400's with 16 KB. The introduction of the 1200XL in 1982 marks the single largest advance in the 8-bit Atari system. It runs a slightly more advanced 6502C microprocessor, and includes a full 64 KB RAM. In 1983 Atari replaced the 1200XL/800/400 line-up with the new 800XL (on the picture) and 600XL with 64 KB RAM and 16 KB RAM respectively. 800XL/600XL was replaced with the new 130XE and 65XE in 1985. While the 65XE is nearly identical to the 800XL in features, the 130XE, however, offers 128 KB RAM.
