The CPU shift operation, yes. I'm talking about shift operations on

That is a property of how the device is wired to the bus. The cpu will
always put a value of 128 on the bus such that D7 = 1 and D0-D6 = 0.

Yes, but is D7 on the left or on the right?

On the bus there is no left or right. There is only D7 and D0.

that there's no macro that will tell how the lines from the CPU to
external memory are mapped.

This is always the same.
