Structural aspects of the System/360 Model 85, I: General organization

The Model 85 is a high-performance system that will execute programs that run on smaller SYSTEM/360 computers. Its basic design includes monolithic circuits, very wide data paths, an 80-nanosecond internal buffer of at least 16K bytes, and a high-speed multiply feature. The system is designed for high throughput over a full range of applications. Among the features that bolster throughput, in addition to the high internal performance, are an exceptionally large main storage, instruction retry, error correction in main storage, and improved diagnostic and maintenance facilities.
