Digital Technical Journal

This journal issue provides a comprehensive overview of the Alpha AXP 64-bit computer architecture and the engineering efforts required to implement it across various systems. Key contents include the Alpha AXP architectural design principles, descriptions of the DECchip 21064 microprocessor, and an examination of hardware prototypes like the Alpha Demonstration Unit. The issue also details the design and performance of the DEC 3000 and DEC 4000 AXP departmental servers, along with technical descriptions of the DEC 7000 and DEC 10000 AXP families. Furthermore, the journal explores software migration strategies, specifically porting OpenVMS and DECnet from VAX systems to Alpha AXP, as well as the GEM optimizing compiler and binary translation tools used to facilitate this transition. Finally, the issue includes a management perspective on the Alpha AXP program and a summary of related technical developments.
