Byte was perhaps the most successful early computer magazine. In its early days, it covered what would have been considered small business computers, hobbyist systems, and the first home computers. This issue from July 1981 is from shortly before the original IBM PC was introduced and includes:
Features
The Santa Cruz Open: Othello Tournament for Computers - Twenty teams compete to create the best Othello program.
Build a Z8-Based Computer with BASIC, Part I - The first in a two part series on building a small computer based on the Zilog Z8 CPU and could be used for microcontroller applications.
Harvesting the Sun's Energy - A type-in program to calculate the proper placement and positioning of solar panels used for heating.
What Time Does the Sun Rise and Set? - A type-in program that will give you sunrise and sunset times for a given latitude, longitude, and date.
Multiprocessing with Motorola's MC6809E - The 6809 was a pretty advanced processor for its time. This was also the processor that the TRS-80 Color Computer used. The 'E' version had a few changes that made it possible to build multiprocessor systems with them. This article describes those changes and creating a multiprocessor system with it.
Computer Simulation of a Solar Energy System - Using a computer to simulate a solar-energy system using the heat transfer equation.
Mountain Computer's MusicSystem - A synthesizer board and software for creating music for the Apple II for $545.
The Atari Assembler/Editor - A detailed look at Atari Assembler/Editor on cartridge from Atari for the Atari 400/800.
DOS Plus: Double-Density Operating System for the TRS-80 - A version of DOS for the TRS-80 Mdel I that supports both double and single density disks and is superior in other ways to the version of DOS supplied with Percom's Doubler.
Nucleus
Editorial: IBM's Personal Computer - A description and commentary on IBM's upcoming personal computer, or at least what was known at the time.
Letters - Letters from readers about bugs in BASIC interpreters, structured programming, self replicating programs, and more.
System Notes - Solving a problem with the OSI Challenger when the terminal width is less than 24 characters.
Programing Quickies - A hurricane tracking program, an energy measurement device and software for the Apple II, and an inflation calculator.
Ask BYTE - Questions answered about generating titles for VHS tapes on a TRS-80 Model I, EPROM programming, I/O expansion on the TRS-80 Model I, and more.
