Comments by Herbert Hellerman

As a member of the original SPREAD committee, I was pleased to see the SPREAD report printed in the Annals of the History of Computing (Volume 5, Number 1, January 1983).

Although SPREAD occurred more than 20 years ago, its consequences are important to this day for several reasons. On the supply side, it laid the basis for the IBM System/360, which showed the technical feasibility and great commercial success achievable with a single, precisely stated architecture or standards-set spanning products with wide ranges of performance, price, and application. Evolving only slowly, the standards have also proved to be remarkably effective over several technologies.

On the consumer side, S/360-370 architecture and its users define a large community that includes most major commercial, government, education, and defense establishments of the Western world. Several supplier...
