This second-source agreement is particularly famous for leading to much <a href="/facts/Advanced_Micro_Devices/CB1G7QTb"> litigation between the two parties</a>. The agreement gave AMD the rights to second-source later Intel parts, but Intel refused to provide the <a href="/facts/Mask_set/xCdRhIod">masks</a> for the <a href="/facts/Intel_80386/ag5eSgWv">386</a> to AMD. AMD <a href="/facts/Reverse_engineering/pmJCV7J7">reverse-engineered</a> the 386, and Intel then claimed that AMD's license to the 386 <a href="/facts/Microcode/XQEsr2X3">microcode</a> only allowed AMD to "use" the microcode but not to sell products incorporating it. The courts eventually decided in favor of AMD.<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a> </p> Wikimedia Commons has media related to Microprocessor second sources. <h2 id="references">References</h2> <ol> <li id="fn:1"><p>John Zysman, Laura Tyson, American Industry in International Competition: Government Policies And Corporate Strategies, Cornell University Press, 1984 ISBN 0-8014-9297-1 page 160 <a href="/wiki/ISBN_(identifier)" target="_blank">/wiki/ISBN_(identifier)</a> <a href="#fnref:1" class="footnote-back-ref">↩</a></p></li> <li id="fn:2"><p>Michael J.
