  There are two versions of SPIM that we can use, one on the UNIX system and the other on the PCs.

  Using SPIM from an ISD PC

  From the Program Manager on the PC, choose "Available Software". Inside that choose "Non-ISD Applications". Inside that you will find "SPIM/SAL for Win32S". This application can be started by a double click in the usual way. The software is "freeware" and is located in the "P" drive on the ISD PCs.

  How to Get SPIM for UNIX

  1. You can copy the file from my public directory:-

     cp /cs/research/graphics/vulcan/home/ucacmsl/Public/SPIM/xspim .
     

  2. Alternatively, you can put the following in your path (see the CS_XTRA_PATH environment variable in your file .uclcs-csh-options):

     /cs/research/graphics/vulcan/home/ucacmsl/Public/SPIM/xspim
     

  3. Alternative, you can download directly from Netscape, choosing the "Save as... Text" option, but then you should

     chmod +x xspim
     

     to make sure that the file is executable.

Having got access to xspim, just type xspim and press return, and the program will start to execute. Wait for the program's window to appear, and you can load in your own .s files from the Load menu, and execute them with the Execute menu.
