I know that the cache line on the Amdahl 470 series was 32 bytes. IIRC that was pretty typical, for those machines that had cache. Not all did at that time. IIRC, the only 360 models with cache were the model 95 and 195. See http://www-03.ibm.com/ibm/history/exhibits/mainframe/mainframe_PP2195.html -- Tom Marchant
