+ZSDOS Adaptation Notes for RomWBW
+---------------------------------
+
+Wayne Warthen
+wwarthen@gmail.com
+
 This file is a log of the work done to adapt the ZSDOS distribution to the N8VEM platforms under RomWBW.  I strongly recommend reviewing the zsdos.pdf file in the Doc directory.
 
 The starting point was the general public release of ZSDOS that is generally available.  The first line of the README file is "ZSDOS-GP.  General Public Release of the ZSDOS 1.x Operating System."
