Pdp8 mri instruction on page border

Question

Does anyone know how pdp8 hardware (and it depends on the model) processes mri instructions on the page border. If your instruction is located at 0177, for example, the program counter is used to read this command, and then increases significantly. If you specify the current page for the address, page 0, instruction page, or page 1 will be used on the page where the computer is located after it has read the instructions, but before it is completed?

Answer 1

In the MACRO-8 Programmer's Guide for computers of the PDP-8 family, the family of references in the name assumes that all models presented are common architecture for the programmer.

From the high-performance 12-bit high definition CMOS microprocessor HD-6120 , the PC is enlarged at the beginning of the instruction, but copied to OL (Output Latch). This means that the current page refers to this manual. A link is, in any case, a valuable source of executable processor description.

Douglas Jones' PDP-8 Digital Equipment Frequently Asked Questions explains that typical assemblers did not provide any way to indicate the value of the "Z" flag and automatically calculated. This reinforces the notion that the instruction links to its own page.
