Hardware design and integrated circuits
Internally the CoCo 1 and CoCo 2 models are functionally identical. The core of the system is virtually identical to the reference design included in the Motorola MC6883 data sheet and consists of five LSI chips:
- MC6809E Microprocessor Unit (MPU)
- MC6883/SN74LS783/SN74LS785 Synchronous Address Multiplexor (SAM)
- MC6847 Video Display Generator (VDG)
- Two Peripheral Interface Adapters (PIA), either MC6821 or MC6822 chips

- 26-3010 - TRS-80 Color Video Receiver introduced in the 1981 Radio Shack Computer Catalog RSC-4 and the 1981 Radio Shack main catalog.
- 16-230 - 13" color TV, model number TC-130. Introduced in the 1983 general Radio Shack catalog, and shown as the CoCo's display in that same catalog's back cover. Also shown on the cover of 1983's Radio Shack Computer Catalog RSC-8 and once in the CoCo section where the Color Video Receiver was still more prominent. Not fully shown in the interior of an RSC until RSC-9 later in 1983.
- 16-231 - a 13" TV. Introduced in the 1985 Radio Shack main catalog. Shown as the display in the CoCo's listing in that same catalog as well as (in 1985's RSC-12 Computer Catalog) on both the cover and the CoCo's own listings.
- 16-232 - a 13" TV/Video Monitor. Introduced in the 1986 Radio Shack main catalog. Shown as the display in the CoCo's listing in that same catalog as well as in 1986's Radio Shack Computer Catalog RSC-15.
- 16-233 - a 13" TV, model number TC-171. Introduced in the 1988 Radio Shack main catalog. Also shown as the display in the CoCo 2's listing in that same catalog and in 1988's Radio Shack Computer Catalog RSC-19.
- Tandy
- CM-8 Specifically made for the CoCo 3. Affordable but no composite input, thus many CoCo 1/2 programs would show in black-and-white.
- RGB-11 Listed in the Color Computer Archive. Perhaps only for composite input use rather than RGB.
- VM-4 Mentioned by Marty Goodman as being "perfectly compatible" with the CoCo 3 - but being monochrome was best for text use. Perhaps any monochrome composite monitor would work.
- Magnavox
- 1CM135
- 8CM505
- 8CM643
- 8CM515 - Analog RGB and composite color. The August 1987 Rainbow ran a favorable review by Ed Ellers (p.140-141) and a recommendation from Marty Goodman (pp. 70,73,75). Cloud-9 still offers a CoCo 3 adapter cable.
- Sony
- KV-1311CR. Howard Medical Computers and Spectrum Projects sold CoCo 3 cables for the analog RGB connection.
- KX-1211HG
