TRS-80 Color Computer

The <a href="/facts/RadioShack/EHzYMpkP">RadioShack</a> TRS-80 Color Computer, later marketed as the Tandy Color Computer, is a series of <a href="/facts/Home_computer/CDEPVd1T">home computers</a> developed and sold by <a href="/facts/Tandy_Corporation/QbPKovTg">Tandy Corporation</a>. Despite sharing a name with the earlier <a href="/facts/TRS-80/zNfQKxnQ">TRS-80</a>, the Color Computer is a completely different system and a radical departure in design based on the <a href="/facts/Motorola_6809/AM6UosAk">Motorola 6809E</a> processor rather than the <a href="/facts/Zilog_Z80/Jeqe2h55">Zilog Z80</a> of earlier models.
The Tandy Color Computer line, nicknamed CoCo, started in 1980 with what is now called the Color Computer 1. It was followed by the Color Computer 2 in 1983, then the Color Computer 3 in 1986. All three models maintain a high level of software and hardware compatibility, with few programs written for an older model being unable to run on the newer ones. The Color Computer 3 was discontinued in 1991.
All Color Computer models shipped with <a href="/facts/Color_BASIC/6lrgIyQt">Color BASIC</a>, an implementation of Microsoft BASIC, in ROM. Variants of the <a href="/facts/OS-9/6dYWMW3f">OS-9</a> <a href="/facts/Computer_multitasking/Q4acPNMv">multitasking</a> <a href="/facts/Operating_system/8XTuvMh2">operating system</a> were available from third parties.
