_{Cover of the March 1980 issue of Byte}

If you were buying a computer magazine in the early 1980s, there's a good chance it was Byte. It tended to be technically oriented with lots of projects to build yourself but it also had reviews and other coverage. Some issues were quite large. The March 1980 issue includes:

Foreground

• Ease Into 16-Bit Computing: Get 16-Bit Performance From an 8-Bit Computer - A look at Intel's 8088 CPU, a 16-bit 8086 on the inside with an 8-bit data bus.


• Electron Behavior in a Chemical Bond - Discussion of and a BASIC implementation of the Schrodinger equation to simulate the behavior of an electron in a diatomic chemical bond.


• Solving Problems Involving Variable Terrain, Part 2: Special Cases, Including Hexagonal Grids - The second part in a series on calcuating map movements with specific examples for game implementation.


• A Power-Line Protection Circuit - A design for building your own surge protector.


• Landing Module Simulation With Random Surface - An implementation of a Lunar Lander type game with M6800 assembler code.
