On Twitter, @hotelzululima suggested Motorola MIKBUG,
introduced in
1974, but IMO it's a monitor, not an operating system.
So the PDP-6 monitor, which booted from DECtape but had no other dependency
on that medium, was not an operating system? It provided multiple timeshared
jobs, so was not a single-program system.
TOS/360 was not an operating system?
Do only disk-oriented operating systems deserve that sobriquet?
