  Conclusions
     We need to acquire some key resources to get the critical
     designs well in hand before they are needed
     Our key risk is in the design of an SLC-aware IOC and SLC
     to EPICS timing that will allow us to intermix the SLC and
     EPICS front-ends. It is also provides a valuable upgrade
     path for the SLC Linac.
     We need to make Interface Control Documents for each
     control subsystem.
