_{Cover of the June 1986 issue of Byte}

Though it gradually became more PC-centric over the years, Byte covered many systems. For whatever reason, it seemed to fade away sooner than some other PC specific magazines. Too bad as this was perhaps the best computer magazine. The August 1986 issue includes:

Features

• Similarity Mapping - A program written in Microsoft BASIC 2.0 for the Macintosh that implements a technique called multidimensional scaling to do things like create maps based on distances.


• Ciarcia's Circuit Cellar: Parallel Interfacing - Part two of a tutorial on parallel interfacing. This part discusses various parallel adapters and uses for them.


• The Definicon 68020 Co-processor - The second and final article in a series which discusses the DSI-020 co-processor board (featuring a 68020 CPU) for IBM XTs/ATs/compatibles. This part focuses on software available for the board.

Theme: Object-Oriented Languages

• Elements of Object-Oriented Programming - A discussion of the features that a language must have to be considered object-oriented.


• A Small Taste of SmallTalk - SmallTalk is an object-oriented language that was briefly popular. It had been around for quite some time by this point but it seemed to reach peak popularity during the second half of the 1980s.


• Objects, Icons, and Software-ICs - Using object-oriented languages to create icon based user interfaces.


• Object-Oriented Languages for the Macintosh - An overview of object-oriented languages available for the Macintosh including SmallTalk, Object Pascal, Neon, ExperCommonLISP, Objective-C, Object Assembler, and Object Logo.


• MacApp: An Application Framework - A framework designed to make software development on the Macintosh easier by implementing most of the Macintosh user-interface standard.

Reviews

• The NCR PC6 - A PC compatible featuring an 8088-2 processor that can run at 4.77 MHz or 8 MHz, 256K to 512K of RAM, two floppy drives or a single floppy drive and 10-megabyte hard drive and optionally a tape backup. Prices range from $2390 to $3690.


• The Sperry PC/IT - An IBM PC AT clone featuring an 80286 CPU with configurable speeds (though the 7.16-MHz 0 wait state option would seem to be the best), a 44.6 megabyte hard drive, a 1.2MB floppy drive, a 360K floppy drive and 512K of RAM for $6044.


• DeSmet C Development Package for the Macintosh - A low-cost ($150) C compiler for the Macintosh.


• TOPSI 2.0 - An implementation of the OPS5 production system language (for creating rule-based expert systems) written in Turbo Pascal for MS-DOS computers.


• Let's C and CSD - An inexpensive ($75) C development package and debugger for XT class machines.
