IT - Virtualization - 4BSD on VAX 11/780 on SimH for Windows 10 x64

Introduction

4BSD (November 1980) offered a number of enhancements over 3BSD, notably job control in the previously released csh, delivermail (the antecedent of sendmail), "reliable" signals, and the Curses programming library. In a 1985 review of BSD releases, John Quarterman et al., wrote:

4BSD was the operating system of choice for VAXs from the beginning until the release of System III (1979–1982) [...] Most organizations would buy a 32V license and order 4BSD from Berkeley without ever bothering to get a 32V tape. Many installations inside the Bell System ran 4.1BSD (many still do, and many others run 4.2BSD).

Steps

  1. Prepare directory strucuture 
    $ mkdir -p /cygdrive/m/Emulators/SimH/
$ mkdir -p /cygdrive/m/Emulators/SimH/mirror/
$ mkdir -p /cygdrive/m/Emulators/SimH/guests/
$ mkdir -p /cygdrive/m/Emulators/SimH/guests/by-platform/
$ mkdir -p /cygdrive/m/Emulators/SimH/guests/by-platform/vax-11-780/
$ mkdir -p /cygdrive/m/Emulators/SimH/guests/by-os/
$ mkdir -p /cygdrive/m/Emulators/SimH/guests/by-os/4bsd/
  2. Install cygwin
    1. install bzip2 (or 7z) and uudecode
  3. Install SimH 4.1 from here. This is another fork project from the original emulator.
    $ cd /cygdrive/m/Emulators/SimH/mirror/
    1. If this is the first time, make a local copy of the simulator
      $ git clone https://github.com/open-simh/simh.git simh-4.1

  4. Prepare data directory
    $ mkdir -p /cygdrive/m/Emulators/SimH/guests/vax-11-780_4bsd
$ ln -sf /cygdrive/m/Emulators/SimH/guests/vax-11-780_4bsd /cygdrive/m/Emulators/SimH/guests/by-platform/vax-11-780/4bsd
$ ln -sf /cygdrive/m/Emulators/SimH/guests/vax-11-780_4bsd /cygdrive/m/Emulators/SimH/guests/by-os/4bsd/vax-11-780
$ cd /cygdrive/m/Emulators/SimH/guests/vax-11-780_4bsd
  5. The simulator program is available in the BIN directory from the compiled git repository. To make life easier, the best is to create a link to the program. I can create a link into /usr/bin or into the guest directory. I will go with the later.
    $ ln -s ../../mirror/simh-4.1/BIN/vax780.exe vax780-4.1.exe
$ ls -laF vax780-4.1.exe
lrwxrwxrwx 1 afberendsen None 36 Feb 19 15:26 vax780-4.1.exe -> ../../mirror/simh-4.1/BIN/vax780.exe*
  6. Unpack the 4BSD tape file 
    $ 7z.exe x 4.0bsd.tap.bz2

  7. Transfer contents of tape to disk
    1. Create tboot.ini file to allow the initial disk set-up and code transfer from the tape.

    2. Start-up the simulator with the initial environment. On the past, when creating the initial disk (rp06.disk), the simulator used to ask for a confirmation to re-write the last track.  
      $ ./vax780-4.1.exe tboot.ini

#
    6. It is recommended that you run fsck to ensure that the 'a' partition is in good health. Run fsck as follows:
      # fsck /dev/rrp0a

/dev/rrp0a

#
    7. Create the user app space partition. Pay attention to use rrp0g.
      # /etc/mkfs /dev/rrp0g 145673
isize = 65488
m/n = 3 500
#
    8. Fill the usr partition from the tape. The two cp commands are used to advance the tape. This version of 4BSD does not have a mt command.
      # /etc/mount /dev/rp0g /usr
# cd /usr
# cp /dev/rmt5 /dev/null
# cp /dev/rmt5 /dev/null
# tar xpb 20
    9. Next we will install a boot block
      # dd if=/usr/mdec/uboot of=/dev/rrp0a bs=1b count=1
1+0 records in
1+0 records out
#
    10. Stop the system. Unmount the /usr partition, sync the I/O buffers. In modern U*X systems, the sync command is called at the shutdown state.
      # cd /
# chmod 755 /usr
# sync ; sync ; sync ; sync
#
    11. Stop the simulator. At the 4BSD prompt, press CTRL-E. This will bring the simulator interface. At the simulator, simple issue the quit command.
      # CTRL+E

  8. Start-up the simulator with 4BSD
    1. Create a new ini file. This time is the Disk Boot ini file: dboot.ini 
      set tto 7b
set rq dis
set lpt dis
set rl dis
set hk dis

    2. (once) Create the boot loader. 
      1. Create a file called boot.uue, with following contents 
        begin 644 boot
