I have made PDF's of three patents awarded to Sony a couple months back. They describe the hardware at the conceptual level of graphics pipelining as implemented in PS2. There are about 50 pages of text description and 40 pages of illustrations (approx. 5mb). I haven't studied them in detail but I expect there may be some insights to the hardware that the manuals left out.
How and where can I share these to those interested?
USA Patents for Playstation 2
Patents are supposedly public documents. They WANT people to have access to that info as it means people can then inquire about licensing the tech or building further and advancing the state of the art. It's the whole point behind patents - make the info public in exchange for a time-limited exclusive right to works based on it. As such, there shouldn't be any problem making the info available however you wish.
