Nonsense. The following two quotes are for OS/360 and MVS,
reaspectively:

"NIP converts any time-slice intervals to timer units, obtains a
primary/master console,"

"Initializing System Consoles

The system console is the I/O device tIle system operator uses to
provide system parameters and otherwise control the initialization
process. Because it is used for operator-to-system communication, it
is actually one of the first devices to be initialized.

The RIM that initializes the system console must locate an available
console, designate it as the master console, and initialize it."

The concept of a NIP console came later.
