And yet still nobody seems to have grokked the fundamental differences
between online systems and event-driven architectures. This is obviously
not the forum for discussions on contemporary software architectures. It
always deteriorates into a deluge of boring and undiscerningposts about
how it's nothing new and was already done back in the day on a S360 with
4K ram and a paper-taper reader held together with gaffer tape.

There have been mainframes running real time applications since the 1960s. Air
traffic control. Airline reservations. Controlling traffic lights (UNIVAC, not
IBM.) These may not be the best examples, but they were the first to come to
mind, and used off the shelf mainframes.

You can make that 'about 30 years ago' - time flies while we’re having fun.

MQ from IBM developed about 20+ years ago helped get from Batch to real
time. You put messages to a queue, and it can run IMS transactions
(including OTMA), CICS transactions, or even batch!. You can put on one
member in a sysplex and get in another member.
It has single put, and also publish/subscribe capability.
