The Apple II series is a family of home computers, one of the first highly successful mass-produced microcomputer products, designed primarily by Steve Wozniak, manufactured by Apple Computer, and launched in 1977 with the original Apple II.
Multiplan was an early spreadsheet program developed by Microsoft. Known initially by the code name "EP", it was introduced in 1982 as a competitor to VisiCalc.
BBC BASIC is a version of the BASIC programming language released in 1981 as the native programming language for the BBC Micro home/personal computer, providing a standardized language for a UK computer literacy project of the BBC. It was written mainly by Sophie Wilson.
Microsoft BASIC is the foundation software product of the Microsoft company and evolved into a line of BASIC interpreters and compiler(s) adapted for many different microcomputers. It first appeared in 1975 as Altair BASIC, which was the first version of BASIC published by Microsoft as well as the first high-level programming language available for the Altair 8800 microcomputer.
The Apple IIGS, the fifth and most powerful of the Apple II family, is a 16-bit personal computer produced by Apple Computer. While featuring the Macintosh look and feel, and resolution and color similar to the Amiga and Atari ST, it remains compatible with earlier Apple II models. The "GS" in the name stands for "Graphics and Sound," referring to its enhanced multimedia hardware, especially its state-of-the-art audio.
ProDOS is the name of two similar operating systems for the Apple II series of personal computers. The original ProDOS, renamed ProDOS 8 in version 1.2, is the last official operating system usable by all 8-bit Apple II series computers, and was distributed from 1983 to 1993. The other, ProDOS 16, was a stop-gap solution for the 16-bit Apple IIGS that was replaced by GS/OS within two years.
Deluxe Paint, often referred to as DPaint, is a bitmap graphics editor series created by Dan Silva for Electronic Arts. The original Deluxe Paint was written for the Commodore Amiga 1000 and released in November 1985. It was eventually ported to other platforms, including an MS-DOS version which became the standard for pixel graphics in video games in the 1990s, the only competitor being Autodesk Animator Pro.
GS/OS is an operating system developed by Apple Computer for its Apple IIGS personal computer. It provides facilities for accessing the file system, controlling input/output devices, loading and running program files, and a system allowing programs to handle interrupts and signals. It uses ProDOS as its primarily filing system. GS/OS is a component of Apple IIGS System Software versions 4.0 through 6.0.1, and was the first true 16-bit operating system for the IIGS.
A cross compiler is a compiler capable of creating executable code for a platform other than the one on which the compiler is running. For example, a compiler that runs on a PC but generates code that runs on an Android smartphone is a cross compiler.
The Print Shop is a basic desktop publishing software package originally published in 1984 by Broderbund. It was unique in that it provided libraries of clip art and templates through a simple interface to build signs, posters and banners with household dot-matrix printers. Over the years, the software has been updated to accommodate changing file formats and printer technologies.
cc65 is a cross development package for 6502 and 65C02 targets, including a macro assembler, a C cross compiler, linker, librarian and several other tools.
Artworx was a Naples, Florida software company that produced and supported a line of computer games from 1981 to 2020. It is named after the founder's given name.

Will Harvey's Music Construction Set (MCS) is a music composition notation program designed by Will Harvey for the Apple II and published by Electronic Arts in 1983. Harvey wrote the original Apple II version in assembly language when he was 15 and in high school. MCS was conceived as a tool to add music to his previously published game, an abstract shooter called Lancaster for the Apple II.
Optimized Systems Software (OSS) was a company that produced disk operating systems, programming languages with integrated development environments, and applications primarily for the Atari 8-bit family of home computers. OSS was best known for their enhanced versions of Atari BASIC and the MAC/65 assembler, both of which are much faster than Atari's products, and the Action! programming language. OSS also sold some products for the Apple II.
Lazer's Interactive Symbolic Assembler (Lisa) is an interactive 6502 assembler for Apple II computers written by Randall Hyde in the late 1970s.

Escape from Singe's Castle, also known as Dragon's Lair Part II - Escape From Singe's Castle, is a computer game for the Amstrad CPC, Commodore 64 and ZX Spectrum home computers, released by Software Projects in 1987. ReadySoft released it for the PC in 1989, and for the Amiga and Atari ST in 1990 and 1991, respectively. An Apple IIGS version was released in 2022. The game is sometimes referred to as Dragon's Lair II, but is not the official arcade sequel Dragon's Lair II: Time Warp.
