At least the 1950’s. That’s when stuff like asynchrony and interrupts were worked out. Dijkstra wrote at length about this in reference to writing code that could drive a teletype (which had fundamentally non-deterministic timings).

If you include analog computers, then there are some WWII targeting computers that definitely qualify (e.g., on aircraft carriers).
