This talks about good reliability of the RC 4000 software. I used an RC 4000 -- which seemed pretty steam-driven in the '80s -- and the immortalized phrase quite heard often enough from our Danish colleagues was "Ze compuder ish all schrewed upp". (Pardon the accent.) As far as I remember that was typically software rather than hardware, and I wonder why the discrepancy. Anyhow, back home, our GEC 4000s¹ were fast and pretty reliable, running the OS4000 operating system. I've never confirmed it, but I assume "4000" was a tribute to RC 4000, given its similar software design and terminology, though Nucleus, (the moral equivalent of?) the microkernel, was in hardware/firmware. It's an interesting counterpoint to the RC 4000 monitor generally described as slow. As the GEC 4000 architecture was later emulated decently fast on M88000s, the speed wasn't just down to the original hardware; such 1970s microkernel-ish designs could work well.
