The Nova can have two terminals (TTI/TTO, TTI1/TTO1). At any moment

it can output to the simulator window. The inactive console cannot
receive input from the keyboard and outputs to an internal buffer

The second terminal input (TTI1) reads data from a disk file. When a
file is attached, the second terminal input will read characters at
the interval specified by the TIME register. Detaching the file, or
reaching end of file, stops input. The POS register specifies the
