Other less recent demos are available which run on sun machines under soar 6.
At the time of writing, these demos work but it is likely that because the soar6 versions of Modsaf and nl-soar are no longer supported, this may well not continue.
To run these demos :-
Change to the /afs/cs.cmu.edu/project/soar/utc/nl/ta/load-files directory and copy the load file for the demo required to current-load.
make sure the corresponding chunk file in /afs/cs.cmu.edu/project/soar/utc/nl/ta/chunks is present and uncompressed.
change to /usr0/soar/ModSAF_20/common/src/ModSAF and start modsaf with the
command modsafll.
