Apple Newton Press (Macintosh) - Manual (Page 83)

General questions
A message says that my computer is running out of memory.
Try closing other applications that may be open. Also try allocating more
memory for use by Newton Press. See your computer’s manual for
information about selecting an application and allocating more memory to it.
I removed old files from the System Folder and now Newton Press won’t start up.
If you have recently removed files from your system, check that you have not
removed files required by Newton Press. See the Readme file installed with
your Newton Press software for a list of files installed with the Newton Press
software and their locations.
