Using Scheme without Schematik:

Sometimes you may have to log in from a terminal or a non-NeXT machine and still run Scheme, even though you can't use the Schematik user interface.  The system administrator can make this easier by doing the following symbolic links (we assume here that Schematik.app is installed in /LocalApps):

ln -s /LocalApps/Schematik.app/kernel/scheme  /usr/local/bin/scheme
ln -s /LocalApps/Schematik.app/kernel/library  /usr/local/lib/mit-scheme
  
If this is done, you can just run scheme from the shell (assuming that /usr/local/bin is in your search path).  The default band is the MIT Scheme dialect.  For SICP, use the command line argument

  -band sicp.com

and for MIT Scheme with compiler use the command line argument

  -compiler

If the above symbolic links are not done, you will need instead of just running scheme to use (the following command should be on one line)

/LocalApps/Schematik.app/kernel/scheme -library /LocalApps/Schematik.app/kernel/library

(again, assuming Schematik.app is installed in /LocalApps, else change as appropriate).  You can select the SICP or compiler options as above.
