Digital Technical Journal

This issue of the Digital Technical Journal (Vol. 9 No. 2, 1997) contains papers focusing on two primary areas: Internet security and software, and the design of high-performance, low-cost Alpha-based workstations.

The security section details the AltaVista Tunnel and AltaVista Firewall, describing their architecture, design for scalability, and performance. It emphasizes the integration of research into commercial products and the balance between security and ease of use.

The workstation section discusses the DIGITAL Personal Workstation series, highlighting the 21174 core logic ASIC which was designed to provide a low-cost, high-performance interface between the Alpha 21164 processor and memory. It also covers design decisions regarding clock synchronization, interrupt controllers, and the use of commodity components to reduce system costs.
