AS MQSeries originated on the IBM Mainframe then I'd say we are in agreement.
As for 1975/76. I was using a DEC PDP-11.
Both the RSX-11 & the RT-11 Operating systems were Async IO based. Writing device drivers for them and also VMS was a really enjoyable experience.
The concept of an AST (Asynchronous System Trap) is really nice. This is a bit of code that gets executed when the I/O you have requested completes.
