And I finished with talking a bit about 1BSD, the very first BSD. I mentioned, that it was not operating system, it didn't provide a kernel nor operating system. It provided a variety of useful programs and utilities for UNIX. 
When looking for software included, I found out that on various ftps you can still download it. So I downloaded one. Size of 1bsd.tar.gz is around 1.2MB, unpacked around 3.4MB.
Update file informs that This tape reflects updates to Thu Jan 19 10:34:29 PST 1978.
1BSD was released as Berkeley UNIX Software Tape (according to read me file). 30 free copies of 1BSD have been sent out and 35 tapes sold for 50 USD, all during late 1977 and 1978. 
The tape came with 2 labels.
First label on the tape:
Berkeley UNIX Software Tape
Jan 16, 1978 TP 800BPI
To extract contents do:
tp xm ./setup; sh setup; tp xm
See accompanying document
Second label on the tape:
The contents of this tape are
distributed to UNIX licensees
only, subject to the software
agreement you have with Western
Electric and an agreement with
the University of California.
Most of the data on this tape has been archived, so that they could write it on tape. This tape included sources and binaries for a quantity of UC Berkeley software. The major items on this tape were the instructional Pascal system and the text editor "ex". Other software includes a modified shell, a new shell, new commands, and a "star trek" game. Machine readable documentation was also included for all programs. The "Pascal User's Manual" and the "Ex reference manual" needed a phototypesetter
if readable copies wanted to be produced. 
Reading Read Me file, you can find out that compiled binaries have been included for most of the software there. (A few of the routines in the directory s6 include system dependent headers and so binaries would be of no use and are not included.) The major programs "pi", "pxp", "px", and "ex-1.1" have the binaries in the directories with the same names.
Each major directory includes a file "READ_ME" describing the software in the directory. There is often a shell script "setup" in the directory to perform one time only operations. The script "install" in these directories placed the software in its standard home.

For recompilation of these programs users could use the scripts "make*", and "comp" and "load" in the directories. Most directories also had "print" scripts, i.e. "printpi", to make a program listing with utility files and programs in a reasonable order.
The suggested way to bring up the software on this tape was to run the install scripts in "pi", "pxp", and "px", and to then install (some or all) of the software from "bin". 
As read me file says, the directory structure goes like this:
pi Pascal translator sourceMore about history of BSD in next parts.
px Pascal interpreter
pxp Pascal execution profiler
eyacc Modified yacc for Pascal
assubs Assembly stuff for Pascal
tests Test programs for Pascal
