You missed two models—the 64 and the 66. They were variations on the 60 and 62, with DAT (Dynamic Address Translation—virtual memory) added. You missed them because it was only one month later that the 60 and 64 were dropped altogether, and the 62, 66, and 70 were replaced with the 65, 67, and 75.

There was also the 69, but that was a joke, with added op-codes such as Halt and Catch Fire, Punch Disk, and Punch Operator.

(There was also a joke about “OS/360: Multiprogramming with a Variable Number of CPUs”, but, dear God, we actually have that now!)
