Thank you for that. I found it enjoyable reading. In return I hope you like reading this page I found that gives a history of the Am5x86 chip that became the making of the AMD company at a time when problems with its K5 chip threatened to pull the company down. http://en.wikipedia.org/wiki/Am5x86 Its good reading, believe me and so are some of the pages linked to it especially the page on the K5 http://en.wikipedia.org/wiki/AMD_K5
