At the far left or top-left boundary of the drawing, the primary AC mains inputs are designated via terminal pads like AC_N (Neutral) and AC_L (Line).
From a top-down perspective, a typical KB 5150 single-sided assembly is divided into clean operational zones engineered to withstand thermal stress while keeping manufacturing costs low. The core structural properties of the board are anchored by its substrate material:
If "top schematic diagram" refers to the physical layout of the System Board (the Component Side), the design reveals a logical flow from the rear expansion connectors to the front power supply.

Here is a useful review and guide regarding the IBM 5150 Schematic Diagram (specifically the System Board/Planar).
The IBM 5150 schematic, whether viewed as a logical block diagram or a physical component layout, reveals a design philosophy rooted in modularity and standardization. By separating the CPU, Bus Control, Memory, and I/O into distinct schematic blocks, IBM created a system that was not only easy to manufacture and service but also highly expandable. The "top view" schematic remains a vital educational tool for understanding the foundational architecture of the modern computer.
