I've restructured the alternative version of PDP-7 Unix so that the

source code is now in src/alt. All the files in src/sys and src/cmd are only annotated versions of the files in scans/. The build/Makefile has been updated so that it can build the original PDP-7 Unix or the alternative version. Phil has fixed the Graphics-2 code, so that there is no need to have any #ifdef code in the original kernel.

+# Alternative prototype file for PDP-7 Unix filesystem layout
+#
+# This one has . and .. but no dd directory entries
+#
+# Entries are one of:
+#    filename f[r-][w-][r-][w-] uid local_file_to_insert
+#    dirname  d[r-][w-][r-][w-] uid [inumber]
+#    device   i[r-][w-][r-][w-] uid inumber
+#    link     l---- inumber
+#
+# The top directory's name is ignored
+# Numeric values are in decimal
+# Contents of each directory ends with a $ on a line by itself
+# Format was inspired by 6th Edition mkfs
+#
