Let's make it simple. Here's that section of my dtab file:
# If you have DL11s, you must give each line an explicit unit number instead
# of using a '?' as above. If you use a '?', autoconfig(8) will start
# assigning unit numbers starting at 0 which will effectively move your
# console to that first line. Start your unit numbers with '1'.
# cn 1 176500 300 5 cnrint cnxint # kl/dl-11 (on mvx11-aa)
cn 1 176500 300 5 cnrint cnxint
cn 2 176510 310 5 cnrint cnxint
cn 3 176520 320 5 cnrint cnxint
cn 4 176530 330 5 cnrint cnxint
cn 5 176540 340 5 cnrint cnxint
cn 6 176550 350 5 cnrint cnxint
cn 7 176560 360 5 cnrint cnxint
Addresses and vectors were taken from the startup menu
presented by the 11/93 at power-up.
