| The ColecoVision is a second-generation home video game console developed by Coleco and released in North America in August 1982, with European distribution under the CBS ColecoVision brand the following year. It offered near-arcade quality graphics and sound, powered by a Zilog Z80 CPU at 3.58 MHz, a TMS9928A/TMS9929A video processor, and SN76489A audio. The system included 1 KB of RAM, 16 KB of video RAM, and shipped with an 8 KB ROM BIOS; games were delivered on cartridges ranging from 8 KB to 32 KB. At launch, it featured twelve titles, including the pack-in hit Donkey Kong, and support eventually grew to approximately 145–170 games released through 1984. One of its standout features was hardware expansion. The popular Expansion Module #1 enabled Atari 2600 compatibility, supported later by a steering-wheel module and the Module #3 Adam add-on, which turned the console into a full home computer. ColecoVision sold over 2 million units by spring 1984—reports vary between 2–3 million overall—and achieved strong early sales, with more than half a million units sold by year-end 1982. However, market saturation and the 1983 crash led Coleco to discontinue it in 1985. |
