You can check out the the whole PISA tree from cvs, for example:

ssh rcf.rhic.bnl.gov
ssh phnxmvd
source .phnx_cshell
klog
setenv CVSLOCAL /phenix/workarea/sullivan/cvs/
cd $CVSLOCAL
cvs checkout simulation/pisa2000

Then run pisa with commands you can find in this crib sheet.

Documentation on the MVD code in pisa is here. Documentation on PISA itself is here.
