- 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
-
Preparation
-
Define shell variables to make life easier...
$ sEmuName=SimH $ sGuestHw=vax-11-780 $ sGuestOs=4-2bsd $ export sEmuName sGuestHw sGuestOs
-
Windows 10 + cygwin
- Install Cygwin with b2zip (or 7z), uudecode, wget
-
Define base directory structure
$ sRootEmulatorsDirectory=/cygdrive/m/; export sRootEmulatorsDirectory
-
macOS
- Install brew
-
Install additional tools. uudecode is installed with macOS already.
$ brew install wget p7zip
-
Define base directory structure
$ sRootEmulatorsDirectory=~/Desktop/; export sRootEmulatorsDirectory
-
Linux
-
Install additional tools. uudecode is installed with Linux already.
$ sudo dnf install -y wget p7zip
-
Define base directory structure
$ sRootEmulatorsDirectory=/Volumes/vol000/; export sRootEmulatorsDirectory
-
Install additional tools. uudecode is installed with Linux already.
-
FOR ALL OSes: Create directory strucuture. Better to create a script called ${sEmuName}_${sGuestOs}_${sGuestHw}.sh. Check the scripts at the end of this page.
$ mkdir -p "${sRootEmulatorsDirectory}/Emulators/${sEmuName}/" $ mkdir -p "${sRootEmulatorsDirectory}/Emulators/${sEmuName}/mirror/" $ mkdir -p "${sRootEmulatorsDirectory}/Emulators/${sEmuName}/guests/" $ mkdir -p "${sRootEmulatorsDirectory}/Emulators/${sEmuName}/guests/${sGuestHw}_${sGuestOs}/" $ mkdir -p "${sRootEmulatorsDirectory}/Emulators/${sEmuName}/guests/by-platform/" $ mkdir -p "${sRootEmulatorsDirectory}/Emulators/${sEmuName}/guests/by-platform/${sGuestHw}/" $ mkdir -p "${sRootEmulatorsDirectory}/Emulators/${sEmuName}/guests/by-os/" $ mkdir -p "${sRootEmulatorsDirectory}/Emulators/${sEmuName}/guests/by-os/${sGuestOs}/" $ ln -sf "${sRootEmulatorsDirectory}/Emulators/${sEmuName}/guests/${sGuestHw}_${sGuestOs}" "${sRootEmulatorsDirectory}/Emulators/${sEmuName}/guests/by-platform/${sGuestHw}/${sGuestOs}" $ ln -sf "${sRootEmulatorsDirectory}/Emulators/${sEmuName}/guests/${sGuestHw}_${sGuestOs}" "${sRootEmulatorsDirectory}/Emulators/${sEmuName}/guests/by-os/${sGuestOs}/${sGuestHw}" $ cd "${sRootEmulatorsDirectory}/Emulators/${sEmuName}/mirror/"
-
Define shell variables to make life easier...
- Install SimH 4.1 from here. This is another fork project from the original emulator. The compilation process can vary, depedning omn the OS.
-
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
Click here to see a run example👇
$ git clone https://github.com/open-simh/simh.git simh-4.1 Cloning into 'simh-4.1'... remote: Enumerating objects: 35175, done. remote: Counting objects: 100% (104/104), done. remote: Compressing objects: 100% (66/66), done. remote: Total 35175 (delta 46), reused 86 (delta 38), pack-reused 35071 Receiving objects: 100% (35175/35175), 78.76 MiB | 21.77 MiB/s, done.

Otherwise, update your local copy
( cd simh-4.1 && git fetch --all -v )

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.
