RSX-11S was the "embedded system OS" of the PDP-11 world (at least as far

That and RT-11.   And MicroPower-Pascal, of which I know nothing apart from its name.   Was that the RTOS used with the T-11 (the first single-chip PDP-11?)   I seem to remember that it was used as the RTOS in the LA-120 printer.   Having a real OS allowed it to do fancy stuff like bidirectional printing, the first DEC printer to do so.
