Cover of the October 1978 issue of Byte


Byte was a long running computer magazine published between the late 1970s and the early 1990s. This issue is "only" around 200 pages but it grew quickly and some issues reached 500 pages and more. The October 1978 issue would have hit the stands almost exactly 46 years ago and includes:

Foreground

  • No Power For Your Interfaces? - Instructions for building a 5 watt DC to DC converter designed to power add-on boards.

  • A "Tiny" Pascal Compiler, Part 2: The P-Compiler - The second part in a series on creating a Pascal compiler.

  • Testing Memory in BASIC - A BASIC program for testing memory (other than the 8K it is loaded in).

  • First Steps in Computer Chess Programming - A tutorial for creating a chess program using Sargon as an example.

  • Linear Circuit Analysis - An article that presents the fundamentals of a frequency domain linear circuit analysis program. This article gives you flow charts and mathematical equations but you have to write your own program.

  • Solving The Eight Queens Problem - The eight queens problem is a chess puzzle the object of which is to place eight queens on an 8x8 chess board in such a way that no queen can take another. This article presents multiple ways for solving the problem.

Background

  • A Memory Pattern Sensitivity Test - An assembly language program that detects pattern sensitivity related errors in memory. These are errors that occur when accessing one area of memory alters another memory location when it contains a certain pattern of bits.

  • PAM/8: A New Approach to Front Panel Design - An article on the design of the front panel firmware of the Heath H8 computer. Of course, the idea of front panels as such would rapidly become obsolete.

  • Assembling The H9 Video Terminal - A terminal was essentially a monitor and keyboard assembly that connected to computers via a serial interface. If you wanted a video display and keyboard input in the early days of computers then this is how it was done. You could buy a terminal fully assembled but given the cost of computer equipment at a time it was common to be able to buy stuff in kit format and assemble it yourself for significant savings. This tutorial covers assembling the H9 Video Terminal which was designed as an accessory for the Heathkit H8 computer though I'm sure it could be used with other machines.
