The author of those photos is the writer of the 'World of VAX' blog (http://worldofvax.blogspot.com/), which I would urge anyone to have a look at if they are interested in mighty operating systems and hardware of olden times, and newer operating systems (Android) of not-such-olden times.
4.3BSD UNIX ('Quasijarus') was available from the SIMH software page ( http://simh.trailing-edge.com/software.html ), but the link has gone. Fortunately, I downloaded Quasijarus before it disappeared, and it is still available via the original site:
"4.3BSD-Quasijarus releases are distributed as tape images on the IFCTF anonymous FTP site ftp://ifctfvax.Harhan.ORG in the /pub/UNIX directory."
The full path: ftp://ifctfvax.harhan.org/pub/UNIX/4.3BSD-Quasijarus0c/
Warning: the FTP site is slow (12.4KB/s download speed) and fussy (it doesn't like 'ls -l') so I have copied the files to my server (see below for a file list).
A good install document:
Install instructions are also contained in file 'setup.txt', from the distribution.
Welcome to the public archive of the International Free Computing Task Force! All materials hosted here are free to the world, i.e., feel free to download whatever you want, but we have to apologize in advance for our very slow and overloaded server and our equally slow and overloaded Internet connection. We also apologize in advance that our FTP server does not currently support restarts. To overcome the limitations of our FTP server and Internet connection, we are making our materials available via an alternate mechanism: CD-R media via snail mail. Specifically, if you E-mail your request to media-orders@ifctfvax.Harhan.ORG and include your snail mail address, we will send you a CD-R copy of our complete archive (currently a set of 4 CDs) for FREE. That's right, we are not even asking you to reimburse us for the cost of media or postage! The reasons for our generosity in this area are very simple: 1. Our limited CPU, disk and network bandwidth is so precious that sending CDs out via snail mail actually costs us *less* than the cost we incur to allow you to download stuff via FTP; 2. We want to have as many copies of our stuff as possible spread as widely as possible so that our work may outlive us. If we get a very large number of requests, then we may have to start asking recipients to cover our cost, but for now that is not a concern, right now the emphasis is on helping ensure preservation. So go ahead and ask for your own CD-R copy of our archive!(Maybe I should have taken that advice - but would they have wanted to send CDs overseas? Methinks not. L.)
