I don't know about guessing, but ChatGPT can deadpan bullshit with the
best of them...
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./
/The DC LO signal is used to transfer data in parallel between the
peripheral devices and the CPU. The signal is active for the duration of
the data transfer, and it is timed with the other signals on the Unibus
to ensure that data is transferred correctly./
/It's worth noting that the PDP-11 was a 36-bit word machine and the DC
LO and DC HI signals were used to transfer 18-bits of data at a time. It
has also a feature of memory mapping, where it can access memory through
a virtual address space, allowing more than one peripheral device to be
connected to the same address on the Unibus./

any good at it.
Anyway how hard would it be for an AI to rewrite a standard MS-DOS to suit a particular
machine? Have they reached the level of sophistication whereby they can analyze code and
rewrite sections?
