Off topic here, but I read an article a while back on the NASA Amigas. The guy at NASA said that when they were looking for systems to use they wrote out to the main manufacturers at the time for details of their systems and how exactly they worked. The likes of IBM and I think Apple suppled very little information but Commodore replied with a ton of documents giving a complete breakdown of how the entire machine worked which is why they chose the Amiga-NASA engineers developed their own custom Zorro cards for use in their Amigas.
