Notes For V3.2-0

RESTRICTION: The PDP-15 FPP is only partially debugged.  Do NOT
enable this feature for normal operations.

WARNING: The core simulator files (scp.c, sim_*.c) have been
reorganized.  Unzip V3.2-0 to an empty directory before attempting
to compile the source.

IMPORTANT: If you are compiling for UNIX, please read the notes
for Ethernet very carefully.  You may need to download a new
version of the pcap library, or make changes to the makefile,
to get Ethernet support to work.
