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)

Mentioned by [[Marty Goodman]] as being [https://archive.org/details/rainbowmagazine-1987-08/page/n71/mode/2up "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.

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:

Audio Digitizers

Audio Output Devices

  • Orchestra-90 CC (26-3143) - Software Affair Stereo Music Synthesizer DAC recreated by Zippster as the CoCoDAC-16
  • Speech/Sound Cartridge (26-3144A) - General Instruments Music and Speech Synthesizer AY3-8913 Programmable Sound Generator (PSG) and an SPO256-AL2 Narrator Speech Processor
  • Symphony-12 - Speech Systems' 4 x AY-3-8912 PSG for 12 channel sound, recreated as the Philharmonic-12
  • Game Master Cart - RetroTinker's Flash ROM and SN76489AN Digital Complex Sound Generator (DCSG)
  • CoCo PSG - Zippster's YM-2149 Software-controlled Sound Generator (SSG)
  • MEGA mini MPI - Zippster's YM-262F OPL3 FM Synthesizer
  • The Voice - Speech Systems' Speech Synthesizer with the Votrax SC-01
  • Super Voice - Speech Systems' Speech Synthesizer device that could sing with a Votrax SC-02 / SSI 263A
  • Real Talker - Colorware Voice Synthesizer with the Votrax SC-01

Video Out

Historical Solutions

Build it yourself

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.

CoCo 3 Only
