Abstract

This report recommends a new family of compatible processors for the IBM product line. A summary of the major points follows. 1. IBM customers' needs for general-purpose processors can be most profitably met by a single compatible [Top of Page 7] family extending from the smallest stored-program core-memory machine to the machine for customers growing beyond the 7094 and 7030. There are processor needs above and below this range; it is not yet evident that these can be compatible with the new processor family. 2. Justification for the compatible family has been established with respect to marketing. It is clearly advantageous to development and manufacturing. Competitors appear to be relying heavily on common programming languages to achieve compatibility. The new processor family guarantees to IBM a compatibility level not achievable by common programming languages. 3. Each processor is to be capable of operating correctly all valid machine-language programs of all processors with the same or smaller I/O and memory configuration. 4. A range of architectural and engineering ground rules have been developed as the foundation for the new processor family. 5. An applied programming plan is outlined that is independent of the number of processors. It is projected that programming systems will be written for only three configurations of the compatible family. 6. To achieve the revenue and profit growth goals, it is concluded that the new processor family must address itself to new, rather than existing, application markets and incorporate existing 1400 series as subsystems whenever possible. 7. Because of the rapid market expansion forecast for the World Trade Corporation (WTC), each element of the new family must consider this market as well as domestic in all phases of development and pricing. 8. For financial reasons, it is concluded that a compatible ";hardened"; family cannot be developed by Federal Systems Division (FSD). 9. An implementation is established in the areas of: a. Interdivisional control including: (1) Architecture. (2) Arbitration. (3) Executive control. (4) Design assignments. (5) Product-control procedure. (6) Standards. (7) PERT (program evaluation and review technique -- see VI, A, 7, a). (8) Marketing requirements. b. Technical development. c. Programming. d. Marketing. e. Introduction planning. f. Security.

I. Introduction

A. Mission and Objectives

1. The SPREAD activity was initiated to establish an overall IBM plan for data processor products. The plan is to encompass all stored- program processor developments in IBM, is to extend to 1970, and must consider the following factors. a. Solid logic technology (SLT), which promises improved cost/performance and reliability. b. New market demands for systems capable of multiterminal, on-line, real-time, multiprogramming operation. c. The explosive growth in applied programming demanded by a larger number of dissimilar systems. d. The 15- 20 engineering groups generating processor products and the need for the establishment of consistency -- i.e., an IBM "image" in the processor field. e. The need to resolve the interactions between present and new processor products across divisional and World Trade lines.

2. Faced with these present problems, the SPREAD task force set as its objectives: a. The definition of a new line of processor products. b. The establishment of logical design, engineering, and applied programming ground rules, within which a processor product line consistent across divisions and World Trade must be defined. c. The creation of a plan for the introduction of these new products that will optimize the conflicting demands of: (1) Market need. (2) Impact on present installed processors. d. The initiation of an appropriate management measurement and control mechanism to assure the implementation of the SPREAD product concepts.
