_{Cover of the July 1989 issue of Amiga Transactor}

Transactor was a long running technical Commodore magazine that mostly covered Commodore's various 8-bit computers. It was published all the way from 1978 to 1989. There was also a spin-off in 1988 titled Transactor for the Amiga. As you probably guessed, it's basically the same kind of thing but for the Amiga.

The July 1989 issue of Transactor for the Amiga includes the following:

Features

• Interrupts: The Heart Of Exec - Carl Sassenrath, the man who wrote the interrupt code in the Amiga, explains how to use interrupts on the Amiga.


• A Vile of Illiteracies - Making fun of mangled grammar. Are two year old drives really two-year old drives or two year-old drives? Plus absurd new (relatively speaking) words.


• Getting A Handle On File Systems, Part 3 - Part three of a series on file systems. This part discusses mapping the file system to physical media.


• Effective Documentation - A standard way to construct a user manual.


• Cubic Spline Interpolation - Using cubic spline interpolation to accurately draw curves. Routines for doing this in C are provided.
