It just would show extreme flexiblity of the chip. It's not a small task to generate realtime video, play music, read a harddisk etc for a chip that wasn't meant for this in the first place. Instead of expensive FPGA or even more expensive custom chips, get a $1 '51 and it will do for you whatever you wish. :) Manufacturer of '51 clones we'll use for the project should sponsor us :)
