IBM 2365 Processor Storage The IBM 2365 Processor Storage is a magnetic-core memory storage unit that was a component of the IBM System/360 models 65 , 67 , 75 and 85 computers, which were released between 1965 and 1968. Storage is implemented using magnetic cores with a storage width of 72 bits , which comprise 64 data bits plus 8 parity bits . The IBM 2365 model 1 contains 131,072 bytes of memory; all other models contain 262,144 bytes. The model 2 could be converted in the field to a model 13. All models other than the model 1 consist of two memory stacks. Addressing for the stacks is interleaved , so the first 64-bit word is in one stack, the second in the other stack, and so forth. This improved performance when doing sequential access . All models other than the model 5 have a cycle time of 750 nanoseconds .Models The various models were used as follows: Model 1 was used on the System/360 model 65 when not used as a multiprocessor. Model 2 was used on the System/360 models 65 and 67-1. Model 3 was used on the System/360 model 75. Model 5 was used on the System/360 model 85. Model 12 was used on the System/360 model 67-2. Model 13 was used on the System/360 model 65 when used as a multiprocessor.Use with the System/360 model 85 The IBM 2365 model 5 is special because the System/360 model 85 accesses memory in 128-bit units, unlike the other System/360 models which supported the IBM 2365, all of which accessed 64-bit units. On the System/360 model 85, the IBM 2365 model 5 operates with a cycle time of 1040 nanoseconds, and two or four of them are required. Because the System/360 model 85 CPU is so much faster than memory, if there are two IBM 2365 model 5 components they are two-way interleaved, and if there are four IBM 2365 model 5 components they are four-way interleaved. Because the IBM 2365 model 5 is internally two-way interleaved, sequential 128-bit memory operations issued by the System/360 model 85 CPU traverse all the memory components before cycling back to the first. The IBM 2365 model 5 is used only with the System/360 model 85 with 524,288 or 1,048,576 bytes of storage.IBM 2385 Processor Storage The IBM System/360 Model 85 , when configured with 2,097,152 or 4,194,304 bytes, uses the IBM 2385 instead of the IBM 2365 Processor Storage. The IBM 2385 has a cycle time of 960 nanoseconds compared to 1,040 nanoseconds for the IBM 2365 model 5.Other IBM products numbered 2385 2385 could also refer to: the processor of the iSeries 9406-170 IBM 33P2385 xSeries x336 Heatsink Copper IBM 53P2385 Internal QIC 60Gb SCSI-attached 5 1/4" backup device
