In my shop when we had the /168, the 3066 was only used during IPL and
doing diagnostic work. In fact, the 168 console was stuck in a back
corner of the computer room and all the real operation was done from
a bank of real 3270s in the center I'm reminded how at Clarkson College in the late 1970s, the S/360-65J IPLed off the 1052 in the back, but after IPL most communication with the system was
done via a more centrally located DECWriter (which of course was three times as
fast and far quieter).
(As a freshman at the time, I had absolutely no clue as to how one
makes a DEC serial device a OS/360 system console. 46 years later, I'm
still not sure I wanna know¡)
Well later on we did it with the AEA option in a 3174. I have no idea of how it
would've been done back then. I'd sure like to know.
Well you could define a TTY on a 2708 but I don't believe that OS/360 could use that as a console... .. on the other hand pretty sure with a PDP-8 -Dave
