A modern Windows desktop PC running a ColecoVision/ADAM emulation program over HDMI offers the absolute best picture and sound quality. Currently I am using a ColecoVision/ADAM emulation program on a 3840 x 2160P desktop computer monitor over HDMI and the picture quality is much better than what I have every experienced in the 20th Century. I know the videogames for the ColecoVision/ADAM only have a native resolution of 256 x 192 interlaced and the PC’s 4K Ultra HD graphics card upscales the image to 3840 x 2160P. In addition, it is a fact that viewing native source material at the sources native resolution is a little bit better quality when compared to upscaling, since upscaling can introduce digital artifacts (However upscaling is required if the display cannot display the native resolution of the source). The reason for the improved picture on a Windows PC is because digital video over HDMI and DVI offers a much better picture quality when compared to analog video that can sometimes be grainy. Back in 1982 the only connection for the ColecoVision was the RF channel 3 and 4 modulated output which combined video and audio over a 75 ohm cable (Using the built in Coleco RF modulator is the worst possible connection for picture and sound quality). In 1983 Coleco came out with the standalone ADAM computer which offered composite video and audio which was a major picture quality improvement. Around 1983 third party companies started offering a composite video output kit for the ColecoVision for those that have soldering skills. In the year 2017 there are companies and individuals selling both composite video and S-Video upgrade kits for the ColecoVision. The advantage of S-Video is that it separates the brightness and color information for an improved picture quality over composite video. There was a company or individual that use to sale a component video output kit for the ColecoVision which is even better quality then S-Video, however its my understanding that the component video kit is no longer in production. Also there is a company that sales a F18A upgrade board that offers true VGA analog 640 x 480i at 60HZ video output for both the ColecoVision and ADAM computer, however this product is currently out of stock and not in production according to one website I visited. Also there is a possibility that it might not be 100% compatible with all the software for the ColecoVision/ADAM. http://codehackcreate.com/store#!/F18A-V1-8-Video-Board/p/14022176/category=0
It is my understanding that the original ColecoVision/ADAM video chip can output 256 x 192 pixels at interlaced component video quality if component video jacks would have existed back in the early 80’s, but even then, that component video signal is analog. The videogames are binary digital videogames and are limited by the Texas Instrument video chip. If Coleco were to make a modern ColecoVision/ADAM console today, there is no doubt in my mind that they would only offer a HDMI output on the videogame console.
What is the absolute best quality video output available for the ColecoVision and standalone ADAM for the year 2017?
I wish the answer to this question was HDMI, however know one as far as I am aware offers a HDMI video card option for the ColecoVision/ADAM. Which is a must have feature for best picture quality on modern desktop computer monitors that only offer HDMI. Even many flat panel screens and projectors are getting away from analog video connections. Now I would be very interested in purchasing the VGA 640 x 480i F18A conversion card for both the ColecoVision and ADAM, but its my understanding this board is out of stock and out of production at this time. In addition, the component video kit for the ColecoVision is out of production from what I understand.
So in the year 2017 the best video quality I can get from the standalone ADAM is its built in 1983 composite video output? After seeing the quality of Coleco ADAM games on a Windows emulator over HDMI, composite video output looks terrible. It looks like someone on EBAY still offers an S-Video board for the ColecoVision, which would be better than composite video. If HDMI, VGA, and component video are not available for the ColecoVision then maybe I might consider getting an S-Video upgrade.
** I also want to be able to use both the Expansion module #1 Atari 2600 adapter and Expansion module #3 ADAM computer with any upgrade service that I get to my original ColecoVision game console. **
Currently the Windows PC ColecoVision/ADAM emulators have both a better picture quality and better controllers when compared to the original ColecoVision/ADAM
Its not just the improved picture quality of ColecoVision and ADAM games on a Windows PC. When I play videogames the 4 directional arrow keys on a $5 Windows keyboard is much better quality when compared to the original ColecoVision/ADAM hand controllers. Also I was playing Slither the other day using a Logitech marble mouse trackball on a Windows PC, and the quality was much better when compared to the original Coleco roller controller. I hate to say it but I am losing interest in the ColecoVision that I owned in 1982 and the ADAM computer expansion module #3 that I owned in 1983, since the Windows PC ColecoVision/ADAM emulator is so much better in many ways.
Maybe one day the ColecoVision/ADAM will have a digital HDMI output with 480i 4:3 quality and also maybe a Windows keyboard could be connected with a Logitech marble mouse for improved videogame enjoyment. When playing ColecoVision/ADAM games on a Windows keyboard with Logitech marble mouse I always place the blame for making mistakes on my poor skill as a game player, versus when using original Coleco game controllers the blame is placed on the controller since sometimes the controller does not operate like it is suppose too.
