The following files should be in the nfx100.* archive:

NFX.EXE     ---  NFX executable
TED.COM     ---  Text editor
TED.DOC     ---  Doc file for TED
README.TXT  ---  This file
FILE_ID.DIZ ---  PCB file description
RM.GIF      ---  Screen capture of Raster Master. View it!
                 (do not delete this file, nfx will not run without it)

Copy all the files into a directory and run NFX. Use the configure option
from the main menu to set the directories and text editor to be used.
