That's what I understand JES and
Multiprocessing support earlier than TSO?
It was before my time, but I read and heard plenty about MVT/MP65, which
predates TSO's rollout by a couple years, I think.
MP65 had challenges: 'sympathy sickness where a CPU problem took down both
CPUs in the complex, kinda sorta anti-redundancy, if

By the way, IHARB is mentioned. It's in maclib. But there's also IKJRB
Normally, I associate the prefix IKJ with TSO. Does anybody out there know
why the TCB mapping macro is named IKJTCB instead of IHATCB. The PSA

This is clearly
TSO was not an original element of [any early flavor of] OS for the
System/360. Its IKJ prefix came a lot later. TSO was initially a
literal, dispensable option; it was not integrated into the operating
system as it now is.
