We anticipate making our new MIPS port of XINU freely available on this site during the summer. (Licensing will be BSD-style, copyright Marquette University and Purdue Research Foundation.) The preliminary versions currently used in courses at Marquette are available upon request for interested faculty at reputable Universities and colleges. E-mail Dr. Brylow if interested.
A revision of the venerable Operating System Design - The XINU Approach textbook is in progress.
