A lot of years ago I remember one post in some web I can not remember about Nintendo 64 manufacture history. I remember that it said that Sillicom Graphics (SGI) had heavy issues during the design/manufacture of the N64 CPU. Because of this, finally the CPU was made by other company, not SGI.

Recently I looked for that post but could not find it. I read other posts about this history but none talks about this SGI issue thing.

Does somebody know anything about this? Maybe is just im remember it wrong.
