I like this project! The PCB looks clean, and has a lean, but complete set of components.<p>160x200 video is a mistake however. Those pixels are twice as wide as they are tall, in NTSC signaling to be perfectly fair. And to be a bit more fair, using that resolution can mean eliminating color "dot crawl" common to devices outputting a composite color video signal, which this little computer appears to do.<p>Now I have written quite a bit of video related code for the Propeller 1 chip featured in this project. It is possible to compromise and double the video resolution to 320x200 and still maintain that crisp look seen in the product photos.<p>The secret is to avoid the color signal interlacing, and or output s-video, which is separated Luma and chroma signals similar to the C64 output signal. Additionally, one can get these little S-video to composite adapters that work pretty well on a non s-video capable display, though the Propeller can offer either video signal just for the asking, and the same video circuit is used for both.<p>With NTSC, anything over 160 pixels in the active video area, which is the signal inside the borders seen in the product photos on the project page, tends to leave fringing between high contrast pixels. Contrast being say, red and blue, which are far apart on the color wheel. This is caused by the low resolution of the NTSC color signal itself being superimposed onto the monochrome Luma signal in the composite, single RCA jack output case.<p>What I did for my video drivers, which can be found on the Parallax site with usually an MIT license, was to simply not interlace the color signal. The spec calls for the color timing to be such that every other scan line is out of phase relative to the prior scan line. This allows for 320 pixel color resolution with the cost being the fringing at high contrast pixel transitions.<p>If the driver simply does not do that, the result is a bit less sharp color, but also no shimmering in the text. That works pretty well with composite on most displays.<p>And when S-video is used, doing the interlace simply improves on the non interlaced color, making it sharper.<p>A propeller chip video generation is almost entirely software driven, which means one can do just about anything with the output signal. It is really a fun device.<p>In my opinion, a 40x25 text display with 7 bits per character, rather than the 4 bits seen on the CODY, would be a whole lot easier to read.<p>The good news is anyone can do that due to how the Propeller is a software driven video device.<p>All that said, the project author may have intended a specific look and feel, and if that is the case, the project looks like a home run!
