Zusammenfassung:A large array of MicroVAX computers will be used for high-speed data acquisition and online filtering in the D0 experiment at Fermi National Accelerator Laboratory. We discuss new developments related to this system, in hardware and particularly in software. The new hardware includes multiported memory boards for faster and more direct input and output of event data. Most of the software development is related to the crucial role of the event filters, requiring an elaborate mechanism for control and monitoring of the FORTRAN based programs running in each of the MicroVAXes.
