Hi,

Don't remember if this was already posted to this list, so, just in case 
it wasn't...

The UNIX System: Making Computers More Productive

http://techchannel.att.com/play-video.cfm/2012/2/22/AT&T-Archives-The-UNIX-System

In the late 1960s, Bell Laboratories computer scientists Dennis Ritchie 
and Ken Thompson started work on a project that was inspired by an 
operating system called Multics, a joint project of MIT, GE, and Bell 
Labs. The host and narrator of this film, Victor Vyssotsky, also had 
worked on the Multics project. Ritchie and Thompson, recognizing some of 
the problems with the Multics OS, set out to create a more useful, 
flexible, and portable system for programmers to work with.

What's fascinating about the growth of UNIX is the long amount of time 
that it was given to develop, almost organically, and based on the needs 
of the users and programmers. The first installation of the program was 
done as late as 1972 (on a NY Telephone branch computer). It was in 
conjunction with the refinement of the C programming language, 
principally designed by Dennis Ritchie.

Because the Bell System had limitations placed by the government that 
prevented them from selling software, UNIX was made available under 
license to universities and the government. This helped further its 
development, as well as making it a more "open" system.

This film "The UNIX System: Making Computers More Productive", is one of 
two that Bell Labs made in 1982 about UNIX's significance, impact and 
usability. Even 10 years after its first installation, it's still an 
introduction to the system. The other film, "The UNIX System: Making 
Computers Easier to Use", is roughly the same, only a little shorter. 
The former film was geared towards software developers and computer 
science students, the latter towards programmers specifically.

The film contains interviews with primary developers Ritchie, Thompson, 
Brian Kernighan, and many others.

While widespread use of UNIX has waned, most modern operating systems 
have at least a conceptual foundation in UNIX.

Subject: [TUHS] Unable to boot v7 UNIX
Message-ID: <CAGWMD9FhF4JBV_=hTdCai71VDSa91cCx397mH8BwpV0i7OaSVQ@mail.gmail.com>

Hi guys, new SIMH (and Research Unix) user here coming from the future
(Linux), haha. Well, as the mail subject says, I have a problem.

After creating a bootable disk from a virgin Unix v7 distribution tape by
following this guide, http://homepages.thm.de/~hg53/pdp11-unix/, and after
umounting the usr file system and halting the machine, SIMH returns:
        HALT instruction, PC: 000002 (HALT)
after running the command:
        pdp11 run.conf
and I cannot boot my 87,9 MB 'system.hp' disk.

I thought the problem was on the final line of 'run.conf':
        run 2002
But when I use SIMH without .conf files and by manually typing the
following commands:
        set cpu 11/45
        set cpu 256k
        set rp0 rp04
        attach rp0 system.hp
        boot rp0
I see the same HALT message too.

I'm currently unning SIMH from Debian/Ubuntu package 3.8.1-5build1. Should
I update to a newest one? Or did I make a mistake when creating my bootable
disk?

Ah crap, this mail was for the SIMH mailing list. Sorry for the confusion.
Anyway, if someone here uses SIMH and knows a solution, I would be happy to
hear it.

Hi Rox,

I cannot reproduce the behavior you describe, sorry. I'm using
32-bit Ubuntu, and compiled SIMH 3.9-0 freshly out-of-the-box.
Everything comes up as it should, including UNIX V7 multi-user
mode.

Did you remember to
  -  substitute 'tm' for the tape in all commands
  -  substitute 'hp' for the disk in all commands
  -  use hptmunix when booting
  -  do a 'mv hptmunix unix' in preparing further bootstraps
  -  'make rp04' and 'make tm' in /dev for creating devices
  -  use 153406 as size for the filesystem on /dev/rp3
  -  copy /usr/mdec/hpuboot as boot block?
Each of these steps is absolutely necessary to successfully
boot the system.

Good luck!

Hellwig
