The out-of-core system block diagram is shown in Figure 1-3; it closely parallels the in-corc cystem in many respects. The out-of-core detectors are much larger than their in-core counterparts, and are located in a fixed position near the core. The cable and eleetronico • portions of the out-of-core system are essentially identical,, and operate in an analogous fashion to the in-core system. ‘
