https://en.wikipedia.org/wiki/IBM_700/7000_series Basically, the IBM 7xx and 7xxx had 4 branches in the family tree. Each incompatible with the other. The IBM 360 was a common design to satisfy all customers with one product. Businesses go the decimal instructions, science labs got the floating point instructions, time sharing sites got virtual memory (67). By the time 31 bit addressing came out, every machine had every instruction available for that model.
