_{Cover of the October 1985 issue of Byte}

Byte was among the earliest computer magazines. It was published from 1975 until 1998. It covered a wide range of computers through its life. The October 1985 issue includes:

Features

• Ciarcia's Circuit Cellar: Build The SB180 Single-Board Computer Part 2: The Software - This single board computer is small enough to fit inside a kids' metal lunchbox of the type common in the 1980s. There is a photo of this one in a Fraggle Rock lunchbox. This computer is based on the HD64180 which is a successor of the Z80. The first article discussed the hardware while this one discusses software. The operating system chosen was Z-System which was compatible with CP/M 2.2 but with additional enhancements.
  
• EGO: A Homebuilt CPU, Part 2: The Hardware - Part 2 of a step by step guide to the design of a CPU.


• Programming Project: Building a Computer in Software - Designing a virtual machine.


• Skycam: An Aerial Robotic Camera System - A look at the computer controlled cameras that traverse wires in stadiums to give an aerial view. I guess these were relatively new at the time.
