Sun still used the term "monitor" in the mid-to-late 80's for the system
firmware:

https://www.typewritten.org/Manual/Sun/SunOS/2.0/man8s/monitor.html
https://www.typewritten.org/Manual/Sun/SunOS/3.2/sun4/man8s/monitor.html

That usage actually survived into the Solaris 11 era:

https://docs.oracle.com/cd/E36784_01/html/E36871/monitor-1m.html

until that man page was finally deleted in 2020 in Solaris 11.4.22 in favor
of references to the OpenBoot PROM user's manual.
