The Aleph detector is installed on the LEP electron-positron storage ring. Its central tracking detector, a time projection chamber (TPC), has about 50000 channels of sampling electronics. The digitized signals are processed by 72 double-width Fastbus modules built around an MC 68020 processor. The time projection processor is described, and the solutions, both hardware and software, adopted to run and manage such a complex system in a Fastbus-VAX environment are discussed. Practical experience with the system is reported. >
