succ412005.Z is a compressed tar archive of the source code to build the SUCC
code version SUCC41sub05. 

There are two subdirectories bsps and config.  These should be moved and the
make file modified to suit local conditions.  Refer to other documents for
details of the tools used to build the system.
In the current sucommon directory the build.h file is left ready to build
a version for a Honeywell based DPU.

4120sub05ram.hex.Z = executable for Penny @ Giles based DPU
4120sub05HAYram.hex.Z = executable for Honeywell based DPU

WARNING
SUCC software for Honeywell based DPUs has diverged from this version.
