? By the time the 370/148 came out 3270s were old hat. 3270-1? Did you mean 3277-1? I never saw one in the flesh, and it was way to small.
OS/VS1 did have some things that MVS did not -- Shmuel (Seymour J.)

At that time it had the macro interface, but as an assembly programmer that was good for me. 3270s were very new at the time and controlling the screen appearance was important. The customer was an Electric company (in a very different cultural environment) and we rather quickly started production use, initially to simply display customer data. Some early mistakes: The IBM marketing people were very much unfamiliar with display terminals and thought that 3270-1 was a good start. I managed to change that immediately! (Who remembers the 3270-1?). We (myself (as an IBM SE) and the customer (both technical and management)) were very happy with how quickly the system became useful. IIRC (which is more difficult at my age) we were the first "real" virtual memory customer in that part of the world. We had about a dozen terminals on the system and had no response problems with the terminals or with batch jobs. CICS, at least in those days, seemed very efficient. Being young and stupid, I liked VS1.
