PDP-11/44 boot prompt

One expects that the operating system executing on the 11/44 will be
RSTS or RX/11 or some other operating system. Hence, the commands
(and isn't this obvious) acceptable at the keyboard are relative to the
operating system. So, which OS is it that is running on your machine?

This information is important to me, since I 1) have an 11/44 being
shipped to me in the next month, 2) have no idea of the OS's that
such a computer can support (though my 11/34a and 11/45 have RSTS/E
and BSD 2.9), and 3) expect, as you, to operate the thing upon arrival.

BTW - mine was used for timesharing applications at a university, so
I expect yours is a fairly large machine. Please, tell me more about your
11/44, such as features of the CPU, the memory size, and peripheral
devices available, and the overall dimensions of the computer. Mine is
said to be some 30 feet long, so if yours is similar, how do you find the
space to put all the parts together. I plan to put mine in the living room
of my home, and my wife, as you might imagine, has some reservations
on the matter!
