Just as the PDP-11/34, the PDP-11/04 was also available with a standard simple so-called "operator's console" and with the more
elaborate "programmer's console".
The PDP-11/04 system with the operator's console is in a BA11-L box, its height is
5.25". The box has a power supply and the 9-slot processor backplane. More room is not available in that box. The PDP-11/04
system with the programmer's console is in a BA11-K box, its height is 10.5". The box has a power supply in the rear (heavy!) and in
the box is room for the 9-slot processor backplane and two other backplanes, one 9-slot and one 4-slot backplane.
