2024-03-02: The wiki ran out of disk space, so things were not working. This has been resolved by adding another 5GB of quota ;-) Thanks to Tim Lindner for reporting the issues.
2020-05-17: If a page gives you an error about some revision not being found, just EDIT the page and the old page should appear in the editor. If it does, just SAVE that and the page should be restored. OS-9 Al (talk) 12:22, 17 May 2020 (CDT)

Core Components
Components in this table are key components used in the Color Computer and for the most part are family members within Motorola's product line to build 6800/6809/68000 microcomputers.
| Part # | Manufacturer | Description | DataSheet | |
|---|---|---|---|---|
| MC6809E | Motorola | The Central Processing Unit (CPU) used in the Coco 1,2 and 3 | ||
| MC6821/MC6822 | Motorola | Peripheral Interface Adapter. Two are used in the Coco to interface the 6809 to IO functions. | ||
| MC6847 | Motorola | Video Display Generator used to generate text on the Coco 1 and 2 | ||
| MC6883 | Motorola | Synchronous Address Multiplexer (SAM) used on the Coco 1 and 2, Also known as SN74LS783. This chip interfaces the system memory with the CPU and VDG. | ||
| MCM68A364 | Motorola | Basic and Extended BASIC ROM chips. These Read-Only Memories (ROMs) are programmed in the factory with the Basic interpreter developed by Microsoft and Microware. | ||
| GIME | Tandy | Graphics Interrupt Memory Enhancement chip. This custom chip provides most of the "personality" of the Coco 3, including the hi-res graphics modes, ability to access more than 64k and the ability to connect to an RGB monitor. | ||
| WD1793 | Western Digital | Floppy disk controller chip. The main component in the floppy disk controller pak, this chip provides functions to control floppy disk drives. |
Additional Components
The following non-core components were used in the Coco models. They are off-the-shelf parts typically used to provide support and minor logic functions on the board. Many of these components will be familiar to electronics experimenters, and are available from several manufacturers.
