This issue of the Digital Technical Journal (Vol. 9 No. 3, 1997) features a variety of technical papers from DIGITAL development teams:

• Parallel SCSI: Discusses advancements in SCSI physical technology including UltraSCSI, expander circuits, improved interconnects (VHDCI and SCA-2), and hot-plugging capabilities.
• Router Clusters: Details the development of router cluster technology designed to provide fast failover (within five seconds) for IP networks to ensure high availability.
• Shared Desktop: Describes a collaborative software tool that enables real-time sharing of 3-D graphics applications across different operating systems (Windows and UNIX) using screen capture and data compression techniques.
• HPF Debugger: Explores the challenges of designing an experimental debugger (Aardvark) for High Performance Fortran, focusing on techniques for reconstructing a single source-level view of a distributed, data-parallel program.
