I never used a 3270 in my early career (1975-78). I joined IBM in 1978 and we still used punch cards built on an 029 card punch. Customers generally got the technology before IBM internal.
In a team of 20 we had a handful of Series 1 emulating a 3270 and you had to book a 30 minute session to input your code. That's when I learned the job deck with a TYPRUN=COPY statement. One way to build up your program between sessions.
