                    Abstract
    The BaBar detector will begin partial operation in late 1997, with full operation expected by Fall of 1998, and continuing for at least five years. Construction has begun on a prototype which will serve as a test bench and beam test system. One goal of this work is to assemble and operate many of the software components needed in the final online system. The system architecture is based on Power PC and Motorola 68040-based single board computers running VxWorks, linked to Sun Unix workstations via ethernet (as well as tests with FDDI and ATM). This early system is based on the Experimental Physics and Industrial Control System (EPICS), which provides control of state transitions and monitoring/adjustment facilities. This functionality is achieved with little software investment: native EPICS utilities are used to develop screen displays and control panels. Emphasis at this time is on the incorporation of reusable code. The first application of this work is the creation of a testbed for the BaBar dataflow R&D, followed by bench test facilities for silicon strip, drift chamber and calorimeter development.
