The first is various historic UNIX distributions not from Berkeley. The second is programs and other operating systems that shipped on or influenced BSD. The distribution is contained on a single DVD that contains all the original content from the original 4-CD-ROM distribution, these two collections of historic software, and a copy of John Baldwin's conversion of the SCCS database contained on the original disk4 to a Subversion repository. Unlike most write-once technology which remains readable for less than ten years, this DVD is written using M-Disc technology which should last for centuries. The price for the DVD is $149.00. I know the $150 USD may sound pricy but the historic2 archive does contain a couple additional copies of Mach! And a bunch of other stuff in there as well, it’s gigabytes of stuff to go through.
