More and more little computers come on the market in the guise of video games, address books, and video players. With each device comes people that take it upon themselves to push them to the limit of how then can be used. In many cases it takes a little hardware to make it all come together. This is one such case.

* Fully programmable FPGA with 50,000 or 150,000 logic gates
