MMURTL-V1.0 - is a book that is very popular among computer programmers interested in the internal workings of a computer operating system. Shown to the left as originally printed, it was previously titled "Developing Your own 32 Bit Operating System" (ISBN 0-672-30655-7) and was published by SAMS/MacMillan. We have renamed the book MMURTL-V1.0 (ISBN 1-58853-000-0) and the printed version is a "Perfect Bind" soft cover (see the additional picture at very bottom of page).  It was renamed because this is the name that the author had originally intended. MMURTL is a bad acronym for Message based MUltitasking Real Time kerneL (to quote the author: "Hey.. all the good acronyms were taken!"). 

This is literally a "how to book" on writing a computer operating system, and includes the assembler and C language code to build one.  In fact, it contains the complete operating system source code, an assembler and C compiler, along with their source code, on the accompanying CD! This is the exact text of the original book except where the author has made very minor corrections where the original text was incorrect (editing mistakes, typos, etc.). You may view the first chapter which is an overview of the book, and the author's goals with the link in the table below. 

The PDF ebook is approximately 2.7 Mb. Total size of all files to download is approximately 8.5 Mb. The printed version is approximately 604 pages, while the PDF version is 667 pages. The printed version also contains a complete index generated by the author.
