The data acquisition system of the ALEPH TPC includes a VAX/VMS computer cluster and 36 intelligent Fastbus modules (ALEPH TPPS) running the OS9 multitasking real-time operating system. Dedicated software has been written in order to reliably exchange information over Fastbus between the VAX/VMS cluster and the 36 TPPs to initialize and co-ordinate the microprocessors, and to monitor and debug their operation. The functionality and the performance of this software will be presented together with an overview of the application that rely on it.
