Installing Saturn Calc, Graph and Word processing:
This software is being distributed on a zipped RL02 disk image file located on the Downloads page of this wiki. If you are using a PiDP-11/70 or Simh, it is easiest to get the zip file with wget. This may already be installed on the Raspberry Pi of your PiDP-11/70, but if not just:
$ sudo apt-get install wget
then to retrieve the zip file into the RSX folder on the PiDP-11/70:
$ cd /opt/pidp11/systems/rsx11mplus/
$ wget http://www.rsx11m.com/Saturn.zip

$ unzip Saturn.zip Archive: Saturn.zip inflating: SaturnRSX.dsk
Now from the console of the running RSX system, type a control E to access simh, and attach the RL02 disk image file to DL0 (rl0 in simh):
>^E
sim>attach rl0 SaturnRSX.dsk
sim>C

Now you can mount the RL02 disk with the Saturn distribution IN RSX:

As mentioned elsewhere in this wiki, Saturn software runs on plain RSX11M as well as RSX11M+. A consequence of that is that named directories are not understood by Saturn tasks and the SET /UIC command determines where it looks for files. This is similar to SET /NONAMED fucntionality in RSX11M+. The Saturn tasks and support files are on DL0:[10,3] on this RL02. The sample graphs, spreadsheets and document files are in DL0:[10,4] and there is an extended set of example graphs in DL0:[10,6] that include maps of all 50 U.S. states with their county boundaries. All of these files total up to ~11,500 blocks so depending on the disk space available on your system you should choose where you want to put the files. If you have plenty of space on your system disk, e.g. DU0: use PIP to copy the files there. If you don't want the map files in [10,6] don't copy them.
>PIP DU0:[10,3]/NV/CD/UF=DL0:[10,3]*.*
>PIP DU0:[10,4]/NV/CD/UF=DL0:[10,4]*.*
>PIP DU0:[10,6]/NV/CD/UF=DL0:[10,6]*.*
In [10,3] there is a command file INSAT.CMD that will do the initial installation of Saturn Software. Once it is installed you can reinstall after a reboot with STARTSAT.CMD that can be called from [1,2]INSPROG.CMD or [1,2]USERPROG.CMD. A global logical SA77: is defined and Saturn looks for a number of .SAT configuration files in SA77:[1,1] This is usually the system disk but if disk space is tight there it can be put elsewhere.

At this point Saturn is ready to start using, but you may need to configure default terminals and graphics devices.
Have fun!
