Tandy Color Computer Roms Details

Tandy Color Computer, known at the time as the TRS-80 Color Computer, is a home computer built into the Motorola 6809E microprocessor. CoCo is part of the TRS-80 series from Tandy Corporation. Color Computer, which is based on the Motorola 6809, is fundamentally different from the TRS-80 I / II / III / 4 and 4p under the name "TRS-80", which of course is called the Z80 processor. Inside the company, Tandy Color Computer was called TRS-90: "9" refers to "6809", but during the sale, Tandy decided to keep the old name for reasons. The color computer with the new processor was still called TRS-80.

The Green Thumb project was co-founded in 1977 by Tandy Corporation and Motorola Semiconductor, Inc. The main goal of the project was to create a cheap home-use computer. First of all, the creation of a low-cost terminal for the Videotex system for agricultural workers was assumed. This terminal could combine a traditional telephone line and a color TV, giving farmers almost what they need in near real time.

Almost at the same time, Motorola launched a new MC6847 video display generator chip. The appearance of this chip enabled the production of a prototype system based on the MC6809 processor. The prototype was introduced in 1978, but contained too many chips, which was not practical for the start. Therefore, Motorola solved this problem by combining the functions of several small chips in a synchronous address multiplexer MC6883. In late 1979, Motorola launched the powerful new MC6809 microprocessor. On the basis of these three chips VDG, SAM and 6809 the terminal AgVision was created. Based on this, Tandy announced on July 31, 1980 the color computer TRS -80. At first glance, it was identical to the AgVision / Videotex terminals: the same design, the same keyboard, and the same layout.
