Unix History


You can download a little diagram of Unix history in PostScript A4 [ http://perso.wanadoo.fr/levenez/unix/unix_a4.ps ] or in PDF A4 [ http://perso.wanadoo.fr/levenez/unix/unix_a4.pdf ]. If you prefer, you can use the PostScript Letter [ http://perso.wanadoo.fr/levenez/unix/unix_letter.ps ] format or the PDF Letter [ http://perso.wanadoo.fr/levenez/unix/unix_letter.pdf ] format.

If you have a plotter you can use this EPS [ http://perso.wanadoo.fr/levenez/unix/unix.eps ] new file, and if you have some problem with it, look here [ http://perso.wanadoo.fr/levenez/eps2ps.html ].

This diagram is only a very simplify unix history. There are a lot more unix like systems than those listed in this chart, maybe 10 times more ! Some years ago, every electronic company has it's own unix system. For example, my company was selling an unix, derivated from another one, and those two are not in this chart because there are too small. So this diagram is only the upper part of an iceberg, with a penguin on it ;-).

Some Home Pages :

* You may be wondering "Why does Steve Jobs appear in this unix history?". Simply because he has made the best unix computer ever : a NeXTcube powered with NeXTSTEP operating system. And now : Mac OS X [ http://www.apple.com/macosx/ ].
