I think you roughly are correct in terms of the history. The System/3{6,8} and others of the era had somewhat fuzzy boundaries on software/microcode/hardware. Same with the AS/400 (iSeries). Intentionally.

The "disaggregated" push is changing things, but just like persistent memory (like Optane, giggle) was supposed to change things. I'm a PGAS (partitioned global address space) person, so the wider pointers and how they're sliced&diced is old hat to me.

Although the work in flat memory space operating systems is so long ago that I no longer even remember their names... A few out of AUS/NZ, iirc? Of course they used other bits for capabilities and access... Happen to remember any of the others? Asking to save myself from digging through bibliographic references.

Are you thinking of Mungi [1] by any chance?
