The ColecoVision can output RGB, composite and S-Video with a modification. Stock consoles only output poor
quality RF video. Please read on for more information.
Like many other consoles of the time, the ColecoVision only offered RF A/V output, with no other stock choice.
For a long time, the only modifications available were composite and S-Video, but more than thirty
years after the console's release, an RGB mod was created! I'll provide links to the mods below, as well
as pictures of the RGB mod. Also, check the links on the right for DIY kits:
RetroFixes now offers installation service for the composite and

RGB Installation: Yurkie on the AtariAge forums offers an installation service for
his Colecovision RGB Board: http://atariage.com/forums/user/23318-yurkie/
RGB DIY Kit: There are a few people around the world working on a DIY Colecovision
RGB Kit. At the moment, none are available for sale, but as soon as I receive more information, I'll post
VGA DIY Kit: There's a board called the "F18A" that replaces the video encoder with a
custom board that outputs 480p VGA: http://codehackcreate.com/store#!/F18A-V1-8-Video-Board/p/14022176/category=0
FPGA Gaming: The Analog NT Mini's custom firmware allows you tp play Colecovision roms, as well as
cartridges with a separate cartridge adapter. This is not software emulation, this is an FPGA
recreation of the Colecovision hardware. I've found it to be amazingly accurate with zero lag. While the NT
Mini is expensive, if you don't already own a Colecovision or the other consoles the NT Mini supports, it
might end up being the cheaper option overall, as it outputs RGB and HDMI.
As an FYI, the RGB and VGA mods are not compatbile with the Atari 2600 adapter, since it bypasses the
internal circuitry. There's an Atari 2600 RGB mod now available though and the 2600 is also supported in the Analog NT
Here's pics of what the Yurkie install looks like (click for full-sized):
As you can see in the pictures, RGBs is easily available right from the board, so you can
use any choice of connector you'd like.
That's it for now. When I have extra time, I'd eventually like to dig deeper into ColecoVision modding and
add comparison pics. Check back every so often for updates (or just follow me on Facebook or Twitter).
