High Quality Content by WIKIPEDIA articles! The Radio Shack TRS-80 Color Computer was a home computer launched in 1980. Despite the name, the 'Color Computer' was a radical departure from earlier TRS-80 Models - in particular it had a Motorola 6809E processor, rather than the TRS-80's Zilog Z80.The Motorola 6809E was a very advanced processor, but was correspondingly more expensive than other more popular microprocessors. Competing machines such as the Commodore VIC-20, the Commodore 64, the Atari 400, and the Atari 800 were designed around a combination of the much cheaper 6502, paired with dedicated sound and graphics chips and were much more commercially successful in the 1980s home computer market. Steve Wozniak once commented that the 6502 was 1/4 the price of the Motorola 6800 when the original Apple was being developed in the late 70s. By 1986 prices for 8 bit processors had dropped dramatically from the late 70s, but the MC6809 was still just over twice the price of a MOS6502.
