Open source 8 bit computer, solution for Africa?

This could be the start of something big. A  "humane" computer solution for Africa --  an extendable, hackable 8-bit general computing platform, designed for both hobbyists and developing nations, that can be displayed on televisions. The Humane Reader can be used as an ebook reader and comes with a 2GB SD card where you can put about 5000 ebooks or, roughly, the entire contents of Wikipedia. While I don't think lack of monitors is the problem down here, all we need is a cheap output to some form of LCD screen. The picture shows the device plugged into some kind of portable DVD player. But we get the picture. Since its all open source computing the schematics are readily available. Perhaps our local LUG will oblige by building a few?
