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./
