Linc and Pdp-8 Instruction Formats

This document serves as a reference guide for the instruction formats of the LINC and PDP-8 computer systems.

LINC Instruction Formats: It details the bit-level structure for LINC instructions, including:

• General instruction formats (including index registers).
• Two-word tape instructions, breaking down the specific bit requirements for the first word and the second word (distinguishing between single-block and multiple-block classes).

PDP-8 Instruction Formats: It provides the bit layout for Memory Reference instructions and explains the bit assignments for Group 1 and Group 2 Operate instructions, including their logical sequences and specific operation codes (e.g., CLA, CLL, CMA, IAC, RAL, OSR, HLT).
