MIT Releases the Source of MULTICS, Father of UNIX

mlauzon writes "Extraordinary news for computer scientists and the Open Source community was announced over the weekend, as the source code of the MULTICS operating system (Multiplexed Information and Computing Service), the father of UNIX and all modern OSes, has finally been opened. Multics was an extremely influential early time-sharing operating system and introduced a large number of new concepts, including dynamic linking and a hierarchical file system. It was extremely powerful, and UNIX can in fact be considered to be a 'simplified' successor to MULTICS. The last running Multics installation was shut down on October 31, 2000. From now on, MULTICS can be downloaded from an official MIT site (it's the complete MR12.5 source dumped at CGI in Calgary in 2000, including the PL/1 compiler). Unfortunately you can't install this on any PC, as MULTICS requires dedicated hardware, and there's no operational computer system today that could run this OS. Nevertheless the software should be considered to be an outstanding source for computer research and scientists. It is not yet known if it will be possible to emulate the required hardware to run the OS."

    Now we can comb the source to find all the places where Linux has stolen from MULTICS too. Give SCO a call, they can help out.

    Surely it's possible, it just may not be much fun or very practical. Unless perhaps that old hardware has some black boxes that talk to spirits or do other magic things.

    How can MULTICS be called the Father Of Unix? Sure, Multics brought some interesting ideas to the party and qualifies for "Unix's Crazy Uncle MULTICS", but a close genetic connection is hard to see.

    Ken Thompson, of course. Multics impregnated him with the ideas, he carried 'em to term and birthed 'em on a PDP-7.

    Calling Unix a "simplified" version of Multics ignores one of the greatest puns in computer history. The name Unix was chosen because it's a castrated version of Multics.

    They talked them into releasing it so it would distract us from Linux. Don't fall for it! Don't spend time porting it! Don't even read the code because they probably planted bugs that are so advanced that just 'more sourcefile.c' would infect you and overwrite your bios and install Anna K pr0n!!!

  14. The perfect emulator by mihalis · · Score: 3, Funny

    In the "Dunnet" adventure game built-in to GNU Emacs there is a VAX cabinet. If you find the CPU board and plug it in the thing runs and you can logon to the system and even execute commands. So I think someone skilled in Emacs Lisp (certainly not me) should implement a MULTICS system inside this game also. Given the birthplace of the original Emacs, this would be somewhat ironic.
