In 2005, Kelvin Sherlock released PNG Floyd, a CDA that captures Apple IIgs screenshots and saves them in the standard Portable Network Graphics (PNG) format. PNG is an open, extensible image format viewable by just about every modern graphics application.
The program listed below is a screen saver that generates random vertical and horizontal lines in low-resolution mode. The lines don?t just appear on the screen. They drag slowly across the screen from one side to the other. The program could also be described as a pattern generator. Pressing the spacebar will clear the screen and quit the screen saver. The program makes use of a pseudo random number generator built into Applesoft BASIC. RND is a function that seems to pick numbers at random.
Listed below is the code for a simple paint program I put together using Applesoft BASIC and the low-resolution graphics built into the Apple IIe. The paint program allows you to draw low-resolution pictures on the screen in 14 different colors.
The following information pertains to the Apple II, II Plus, IIe, IIc, and IIgs computers. This is a must read for anyone frustrated by the lack of software commercially available for the venerable Apple II. Three primary file types are discussed: ShrinkIt files, binscii encoded files, and disk images.
Applesoft BASIC is a versatile language. It is possible to design simple games using low-resolution graphics. You won?t be winning any awards for graphics but it is an interesting way to spend an afternoon. Listed below is a Pong program I designed. It uses the up arrow and down arrow to control the paddle (vertical orange line). It is a Pong-type game very similar to swash.
Here is a cool program called ][ GIF, version 1.0, by Jason Harper. The program makes it possible to view a GIF on an Apple IIe. The Apple IIe doesn?t have much graphical capabilities compared to modern computers but in its time, it was a quantum leap above many of its competitors.
