The AS/400, the successor of the System 3 and System/38, hasn't been around 40 years. I don't even think the IBM 360 was around 40 years ago.

The System/360 was introduced April 7, 1964. They were called third-generation machines - the first true multi-tasking machines.

I was a sales rep for AT&T (dont ask, we all knew our stuff - 3B2's and 3B3's etc.- SUCKED!!!)in the mid-80's. We sold against System 36's and System 38's all the time. The AS-400 came out about 1988 or so.
