as the video game crash of 1983. Many of the third-party developers formed prior to 1983 were closed, and Mattel and Coleco left the video game market by 1985. In September 1983, Atari sent 14 truckloads of unsold Atari 2600 cartridges and other equipment to a landfill in the New Mexico desert, later labeled the Atari video game burial. Long considered an urban legend that claimed the burial contained millions of unsold cartridges, the site was excavated in 2014, confirming reports from former Atari executives that only about 700,000 cartridges had actually been buried. Atari reported a loss for 1983 as a whole, and continued to lose money into 1984, with a loss reported in the second quarter. By mid-1984, software development for the 2600 had essentially stopped except that of Atari and Activision. Warner, wary of supporting its failing Atari division, started looking for buyers in 1984. Warner sold most of Atari to Jack Tramiel, the founder of Commodore International, in July 1984 for about , though Warner retained Atari's arcade business. Tramiel was a proponent of personal computers, and halted all new 2600 game development soon after the sale. The North American video game market did not recover until about 1986, after Nintendo's 1985 launch of the Nintendo Entertainment System in North America. Atari Corporation released a redesigned model of the 2600 in 1986, supported by an ad campaign touting a price of "under 50 bucks". With a large library of cartridges and a low price point, the 2600 continued to sell into the late 1980s. Atari released the last batch of games in 1989–90 including Secret Quest and Fatal Run. By 1986, over Atari VCS units had been sold worldwide. The final Atari-licensed release is the PAL-only version of the arcade game KLAX in 1990. After more than 14 years on the market, the 2600 line was formally discontinued on January 1, 1992, along with the Atari 7800 and Atari 8-bit family of home computers. Hardware Console The Atari 2600's CPU is the MOS Technology 6507, a version of the 6502, running at 1.19 MHz in the 2600. Though their internal silicon was identical, the 6507 was cheaper than the 6502 because its package included fewer memory-address pins—13 instead of 16. The designers of the Atari 2600 selected an inexpensive cartridge interface that has one fewer address than the 13 allowed by the 6507, further reducing the
