Unix Archive

Here’s an archive of older versions of Unix, including version 6 (which is what I cut my teeth on, on a PDP-11/45 at the National Bureau of Standards).

Obligatory story: Version 6 was before automatic file system repair — when the system crashed (as it did, sometimes at the hands of not-very-experienced summer students like me or my friend Jack), more often than not it was necessary to repair the file system by hand, using ncheck, icheck and clri. When fsck came along, this wacko thing from Berkeley, none of us trusted it….

Errata: I meant dcheck, of course, what was I thinking?
