This is a demonstration of version 2 of my digital video player for the Tandy Color Computer 3. Version 1 just never performed as well as I liked, so I revised it in preparation for this year's CoCoFEST! on May 21-22 2011 in Elgin, IL. See http://www.glensideccc.com/ for event details -- I'll be there with a live demonstration for those interested in seeing it in person. I hope you will be as pleased with the revised performance as I am!
The video playback shown is 128x192 in 16-colors. The video is updated 60 times per second, although obviously not every update covers an entire frame. The audio playback is at 11040HZ. Audio samples are 8-bits each, although the stock CoCo3 audio DAC is only 6-bits. Each minute of video requires roughly 2-2.5MB of storage.
Is that Coco 3 the vanilla 6809E, or does it have the faster Hitachi 6309 replacement CPU?

@deathshadow60 I think that particular box might have a 6309, but the player code is purely 6809 code.

Atari 2600, Galaxian table top, and a coco. You could easily be my best friend :)
Very impressive work for the Coco. Very impressive. I'm amazed by what you fellows on the coco list are able to do. Amazing work :)

@atarileaf Ha! You have no idea! Maybe I should pan the camera wider next time... :-)
