Caldera releases original unices under BSD license

Posted by Nik on from the born-free dept.

q[alex] writes "Caldera International has done a very good thing. They have released the "Ancient" Unices they inherited when they purchased SCO under a "BSD-style" license. The license is available here, instructions on finding the source are here. Caldera (and before that SCO) had required people to obtain a free (as in beer) but somewhat restrictive license in order to get these old sources. The new BSD-style licensing only applies to the 16-bit PDI-11 versions and some of the early 32-bit releases (excluding System III and System V), but it's still very cool."

    Never would have thought Caldera would have done something as community-oriented as this, given their history of late.

    However, a big thank-you from this Slashdot reader for their act. I appreciate it, and I know I'm not alone...

    I don't mean to sound like a stick in the mud here, but why exactly is this cool? This source code was obviously available before, for people who actually needed it. Why, then, is the simple fact that anyone can get to it now a "cool" thing?

    Will this spawn development of breakthrough products? Will this help administrators of these old system finally take control of their network?

    Or is this just another geek trophy to have, print, wave around over coffee, and ultimately collect dust on shelves full of other useless time-wasting trinkets?

      It is great to have this available for study. And, this might inspire a whole new generation of PDP-11 emulators so you can sit down and actually run the original bits (emulation of an ASR-33 not considered mandatory).

      Computer Science would also be served well if the original Multics sources/binaries were released. Although it would be much harder to write a Honeywell emulator!

  3. Reading the install notes..... by Jester99 · · Score: 4, Insightful

    is really amazing.

    If you ignore the instructions for copying the system from magtape to disk (!), everything else looks very similar to the install notes for most modern unices today....

    They tell you to 'cat' files to the printer, 'tar' together items for backup storage, 'sync' before you turn the machine off, and remember to check 'df' regularly to make sure your users don't fill up the disk, and clean out the /tmp directory periodically.

    Reading documentation written 30 years ago which almost hasn't changed at all is really a beautiful thing. (Well, some things have changed. During bootup, the 'mem' line reports user-available memory in bytes. :)

    Hats off to the developers of a system which is so flexible that hasn't really needed interface changing at all to adapt to 30 years of great changes in computer design and usage!
