IT - Virtualization - 2.9BSD on PDP-11 on SimH 4.1 for Windows 10, macOS, and Linux

NOTICE

I am continually working to improve the approach for virtual machines. Check the most recent post to have an idea on how things are changing. Also, please, leave a comment when you find something that need to be improved.

Virtualization

Pending

  • Additional disks
  • Network
  • ps hangs
  • /etc/reboot (and /etc/shutdown) is not working
  • Instructions for Windows (no Cygwin), *BSD

Steps

  • bold text is user input from the keyboard
  • red text are control characters typed by the user
  • blue text is automatic input from SimH input processing
  • fuchsia text are automatic control characters input from SimH input processing
  1. Preparation
    • Windows 10 + cygwin
      1. Install Cygwin with b2zip (or 7z), uudecode, wget
      2. Define base directory structure 
        $ sRootEmulatorsDirectory=/cygdrive/m/; export sRootEmulatorsDirectory
    • macOS
      1. Install brew
      2. Install additional tools. uudecode is installed with macOS already. 
        $ brew install wget p7zip
      3. Define base directory structure
        $ sRootEmulatorsDirectory=~/Desktop/; export sRootEmulatorsDirectory
    • Linux
      1. Install additional tools. uudecode is installed with Linux already. 
        $ sudo dnf install -y wget p7zip
      2. Define base directory structure
        $ sRootEmulatorsDirectory=/Volumes/vol000/; export sRootEmulatorsDirectory
    • FOR ALL OSes: Create directory strucuture
      $ mkdir -p "${sRootEmulatorsDirectory}/Emulators/SimH/"
$ mkdir -p "${sRootEmulatorsDirectory}/Emulators/SimH/mirror/"
$ mkdir -p "${sRootEmulatorsDirectory}/Emulators/SimH/guests/"
$ mkdir -p "${sRootEmulatorsDirectory}/Emulators/SimH/guests/pdp-11_2-9bsd/"
$ mkdir -p "${sRootEmulatorsDirectory}/Emulators/SimH/guests/by-platform/"
$ mkdir -p "${sRootEmulatorsDirectory}/Emulators/SimH/guests/by-platform/pdp-11/"
$ mkdir -p "${sRootEmulatorsDirectory}/Emulators/SimH/guests/by-os/"
$ mkdir -p "${sRootEmulatorsDirectory}/Emulators/SimH/guests/by-os/2-9bsd/"
$ ln -sf "${sRootEmulatorsDirectory}/Emulators/SimH/guests/pdp-11_2-9bsd" "${sRootEmulatorsDirectory}/Emulators/SimH/guests/by-platform/pdp-11/2-9bsd"
$ ln -sf "${sRootEmulatorsDirectory}/Emulators/SimH/guests/pdp-11_2-9bsd" "${sRootEmulatorsDirectory}/Emulators/SimH/guests/by-os/2-9bsd/pdp-11"
$ cd "${sRootEmulatorsDirectory}/Emulators/SimH/mirror/"
  2. Install SimH 4.1 from here. This is another fork project from the original emulator. The compilation process can vary, depedning omn the OS.
    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. 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.
