The Digital Technical Journals reference library

This is a machine-readable set of all 42 of the Digital Technical Journals, scanned from paper originals.

The machine-readable set was created as a CD for the 2006 HP OpenVMS Advanced Technical Symposium in Nashua.

As of April 2016 the originals have been re-scanned and made searchable, using the OCR capabilities of Acrobat DC Pro.

These journals provide an in-depth understanding of why computer systems work as they do. They provide a unique insight into the rigours of the design process and the architectural approach to implementation. Most of the articles describe in detail the very first time that any of these products and processes were created. The engineers and scientists involved have made the effort to clearly describe what they did, how they did it and, crucially, why they did it the way that they did it.

The journals document the work of people at Digital Equipment Corporation with the ability, skills and determination to "do it right". CPUs , memory, I/O, storage and networks are all changing dramatically in terms of performance and capacity, yet the fundamental principles hold true. As a result, the systems and software (such as OpenVMS itself) have been able to evolve while continuing to deliver mission-critical availability and performance. They have also maintained an astonishing level of backwards compatibility across a wide range of hardware platforms and machine architectures. These unique achievements are due to the outstanding design skills of the engineers, their insights, their clear understanding of the core issues and their ability to plan for the future.

Please also admire the work of the editors and technical authors who worked with the engineers and scientists to create the Digital Technical Journals - and don't miss the artwork on the covers.

As an educational resource to illustrate the art of computer systems engineering these journals are hard to beat.

This document scanning project would not have been possible without the assistance of many people, especially Sue Skonetski, Nic Clews, Paul Dolan, Dave Foddy, Ian Miller, Tim Pass and all those kind enough to donate copies.

My grateful thanks to them all.

Engineering Milestones in Digital's History - insert

Engineering Milestones in Digital's History

Digital Equipment Corporation was founded in 1957. Since then, Digital's engineers have consistently delivered outstanding computer systems, network products, software, peripherals, storage systems, and semiconductor devices. This special section in the tenth anniversary issue of the Digital Technical Journal chronicles the engineering milestones in Digital's history from 1957 to May 1995. Many industry "firsts" can be found in this chronology, beginning with the PDP1 minicomputer through the record-breaking Alpha microprocessor. The milestones noted here represent a range of products and many years of computer engineering design and development.

A letter to readers of the Digital Technical Journal

This issue is the last Digital Technical Journal to be published. Since 1985, the Journal has been privileged to publish information about significant engineering accomplishments for DIGITAL, including standards-setting network and storage technologies, industry-leading VAX systems, record-breaking Alpha microprocessors and semiconductor technologies, and advanced application software and performance tools. The journal has been rewarded by continual growth in the number of readers and by their expressions of appreciation for the quality of content and presentation.

The editors thank the engineers who somehow made the time to write, the engineering managers who supported them, the consulting engineers and professors who reviewed manuscripts and made the process a learning experience for all of us, and, of course, the readers who are the reason the journal came into existence.

With kind regards,

Jane Blake (Managing Editor), Kathleen Stetson (Editor), Helen Patterson (Editor)
