Hi Patrick,

Really testing my (fading) memory!  This was on a System3 Model 15D.  
I'm sure there wasn't anything like the object authorities on the 
current IBM i. To give you an idea, here's a quote from 
https://en.wikipedia.org/wiki/IBM_System/3

The system could only run two programs simultaneously, except for the 
model 15 or systems running the Communications Control program, CCP. The 
CCP was a system control programming feature that allowed to support an 
online network ofterminals 
<https://en.wikipedia.org/wiki/Computer_terminal>.

What I'd call /minimal/ operating system.  These days, I sort of 
correlate MRT to a web server, which calls a program to handle a 
particular web page.
