  We integrated an injector linac control system to the SPring-8 standard
system on September 2000. As a result of this integration, the SPring-8
accelerator complex was controlled by one unified system. Because the linac was
continuously running as the electron beam injector not only for the SPring-8
storage ring but also for New SUBARU, we had to minimize the hardware
modification to reduce the time for the development and testing of the new
control system. The integration method was almost the same as that of the
integration of the booster synchrotron. We report here on the integration of
the linac control system with emphasis on the upgrade of the VMEbus controllers
and software involving the operating system Solaris 7 as the real-time OS.
