On Twitter, @hotelzululima suggested Motorola MIKBUG,

1974, but IMO it's a monitor, not an operating system.
Given the constraints of the systems of that time (speed, memory size,

might be tricky to specify.
Here's another interesting marginal candidate:
DEC MPS
A three board Omnibus set that contained an Intel 8008, memory and IO
- it had a resident monitor on the KC341 control panel.
