First of all, utterly brilliant! An effort to be lauded in every possible way! That being said, I think there might be better ways to do the video... Excerpt: "So I looked in my drawers and pulled out four 7400 chips—two multiplexers and two parallel-to-serial shift registers. I could set eight pins of the 1284P in parallel and send them simultaneously to the multiplexers and shift registers, which would convert them into a high-speed serial bitstream. In this way I can generate bits fast enough to produce some 215 distinct colors on screen. The cost is that keeping up with the video scan line absorbs a lot of computing capacity: Only about 25 percent of the CPU’s time is available for other tasks." You know, you could have this computer communicate with a Raspberri Pi over USB, and have the Raspberry Pi act as the computer's "video card". Doing this and only sending parts of the screen that changed (like VNC) might allow many more colors at much higher resolutions, and might not tax the CPU as hard (especially at points in time when the screen doesn't need to be updated)... you know, use the Raspberry Pi as a frame buffer of sorts... But, that being said, I once again reiterate with respect to the work: Utterly brilliant! An effort to be lauded in every possible way!
