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 Multiplexer (SAM)
- MC6847 Video Display Generator (VDG)
- Two Peripheral Interface Adapters (PIA), either MC6821 or MC6822 chips

- Radio Shack
- 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
- 26-3512 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.
- 25-8056 RGB-11 Listed in the Color Computer Archive. Perhaps only for composite input use rather than RGB.
- 26-3211 VM-2 Monochrome (green-screen) composite. Had "Tandy TRS-80" branding; part of the brief attempt to hold on to "TRS-80" while still moving to "Tandy" instead of "Radio Shack". Introduced in RSC-14 in 1985; intended for the Tandy 1000 and the Model 100's Disk/Video Interface rather than the CoCo, but when the CoCo 3 complete with composite port came along two years later, it could be an inexpensive option for those intending their CoCos for productivity, telecom, text adventures, and monochrome graphical games like Daggorath and Nebula, and wanted the higher resolution than a TV could provide.
- 25-1020 VM-4 Successor of the VM-2. Introduced in RSC-17. Mentioned by Marty Goodman as being "perfectly compatible" with the CoCo 3 - but, again, being monochrome, was not ideal for most games or graphics. Perhaps any monochrome composite monitor would work.
- Magnavox
- 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.
- 1CM135 - Replaced the 8CM515, adding stereo sound input, Commodore-style S-Video with chorma-luma input, and CGA RGB. Recommended by Marty Goodman in the March 1991 Rainbow.

Build it yourself
- CoCo 1 Monochrome Video
- CoCo 1 composite video
- Coco 1 S-Video Circuit, Simplified (requires disabling RF) Convert to Composite by adding a 470pf capacitor between the yellow and blue lines and replace the S-Video connector with an RCA connector with center connector on the yellow side of the new capacitor.
- CoCo 1 and 2 S-Video and Composite Out Circuit
- CoCo 2 S-Video and Composite Out Circuit
- CoCo 1 or 2 YPbPr/YUV Component Out Circuit
- CoCo 3 RGB -> SCART Use with a SCART to HDMI adapter.
Current Solutions to Purchase
- Video without RF Box Use existing RF out on your CoCo 1, 2, or 3 into your TV tuner.
- RGBtoHDMI Requires Pi Zero, RGBtoHDMI hat board, and Analog board. Mostly used with CoCo 1s and 2s, but can also be used for PAL CoCo3s to simulate NTSC artifact colors.
CoCo 1 or 2 Only
Note that these CoCo 1 and 2 solutions require installation.
- CoCoVGA for CoCo 1, 2, MC-10, Dragon A FPGA-based solution that outputs VGA.
- CocoDV for Coco 1 or 2 An FPGA-based solution that plugs into the MC6847 Video Display Generator IC socket on the board and provides HDMI video. Also adds extra functionality like sprites and fonts. Order via email from AC-8 Bit Zone.
- Composite Video Out boards for CoCo 2
CoCo 3 Only
- GIME-X for CoCo 3 Replace your GIME chip with this FPGA-based solution that adds VGA output. Also has even more video modes and allows overclocking the CoCo.
- RGB2NTSC CoCo3 to (a better) Composite and S-Video
- Switch-a-roo CoCo3 to SCART cable Use with a SCART to HDMI adapter.
