Byte (September 1985)

Byte (September 1985)

Subtitled "The Small Systems Journal", Byte covered a wide variety of home and hobby computers in its earlier days. Towards the end of its life, it became more of a standard PC magazine. In 1985, however, it was large (almost 500 pages for this issue) and covered a lot. The September 1985 issue includes:

Features

• Ciarcia's Circuit Cellar: Build the SB180 Single-Board Computer - The SB180 was a single board computer featuring a 6 MHz HD64180 processor from Hitachi that was Z80 code compatible and could directly address 512KB of RAM (as opposed to the more limited 64K that the Z80 could directly address). This first part of a two part series focuses on the hardware.


• Programming Project: An Analysis of Sorts - A look at the algorithms and speed of various sorting algorithms including the selection sort, merge sort, and quick sort.


• The DSI-32 Coprocessor Board, Part 2: The Software - The second of a two part series on the DSI-32 co-processor board for the IBM PC. The co-processor in this case is the National Semiconductor 32032. This part focuses on the software.


• An Algorithm for Disk Caching with Limited Memory - A set of C-language routines for caching data from floppy disks.


• Astrophysical Number Crunching - A history of the use of "personal computers" in theoretical astrophysics. Or at least the history from one astrophysicist's perspective.

Themes

• EGO: A Hombuilt CPU, Part I: The Software - The first of a two-part series on the author's experience crating a homemade CPU. This part focuses on the instruction set.


• The Quarter-Meg Atari 800XL - Upgrading your Atari 800XL all the way to 256K and turning some of that RAM into a RAMdisk. This article includes a parts list and instructions for constructing your own 256K expansion.


• A Parallel-To-Serial Printer Port Adapter - Instructions for building a $35 parallel-to-serial printer port adapter that will allow you to connect a serial printer to your parallel port.

Reviews

• Reviewer's Notebook - A brief look at upcoming products including the HP 110 Portable Plus and a WORM drive featuring a 400MB capacity for a mere $5000.


• The Kaypro 16 - A portable PC compatible featuring two floppy drives (or one flopp drive and one hard drive) and 256K of RAM for $2295 to $3295 depending on whether you want that hard drive or not.


• The Osborne 3 - Another portable PC compatible featuring an 80C86 running at 3.5 MHz, two 5.25" disk drives, 256K RAM and an LCD (80 characters x 16 lines). It's only partially PC compatible though and will not work with programs that directly address the hardware.


• WordStar 2000 - A new easier to use version of this word processor for MS-DOS 2.0. It cost between $500 and $600 depending on whether you got the plus version or not.


• XyWrite II Plus - A less expensive word processor ($300). It was somewhat unique in that many of its commands were done through a command line interface vs. menus.


• Filevision - A visual data management system for the Macintosh.
