I telephoned the customer service department at a railway company. I think
the person I spoke to knew less about trains than this thing knows about
a PDP-11. Maybe they are using AI to do telephone answering now?

Prompt: /Describe the purpose of the DC LO signal in the DIGITAL PDP-11
Unibus/
Response:
/The DC LO signal, also known as the "Data Bus Low" signal, is a signal
that is used on the Unibus of the Digital PDP-11 computer. The Unibus is
a bus architecture that was used in the PDP-11 computer to connect
various peripheral devices, such as memory, disk drives, and other I/O
devices, to the central processing unit (CPU)./
/The purpose of the DC LO signal is to provide the lower 8 bits of data
that are transferred between the peripheral devices and the CPU over the
Unibus. It is used in conjunction with the DC HI signal, which provides
the upper 8 bits of data, to form a 16-bit wide data bus. Together, the
DC LO and DC HI signals provide the mechanism for data transfer between
the peripheral devices and the CPU on the PDP-11./
