The Apple II is an early personal computer that was created by Apple Inc. It was one of the first successful mass-produced microcomputer products, and it played a significant role in the early development of the personal computer industry. It has an 8-bit microprocessor.
The Commodore 1541 is a floppy disk drive which was made by Commodore International for the Commodore 64 (C64), Commodore's most popular home computer. The best-known floppy disk drive for the C64, the 1541 is a single-sided 170-kilobyte drive for 5¼" disks. The 1541 directly followed the Commodore 1540.
Software cracking is an act of removing copy protection from a software. Copy protection can be removed by applying a specific crack. A crack can mean any tool that enables breaking software protection, a stolen product key, or guessed password. Cracking software generally involves circumventing licensing and usage restrictions on commercial software by illegal methods. These methods can include modifying code directly through disassembling and bit editing, sharing stolen product keys, or developing software to generate activation keys. Examples of cracks are: applying a patch or by creating reverse-engineered serial number generators known as keygens, thus bypassing software registration and payments or converting a trial/demo version of the software into fully-functioning software without paying for it. Software cracking contributes to the rise of online piracy where pirated software is distributed to end-users through filesharing sites like BitTorrent, One click hosting (OCH), or via Usenet downloads, or by downloading bundles of the original software with cracks or keygens.
The TRS-80 Micro Computer System is a desktop microcomputer launched in 1977 and sold by Tandy Corporation through their Radio Shack stores. The name is an abbreviation of Tandy Radio Shack, Z80 [microprocessor]. It is one of the earliest mass-produced and mass-marketed retail home computers.
The Atari 8-bit family is a series of 8-bit home computers introduced by Atari, Inc. in 1979 with the Atari 400 and Atari 800. As the first home computer architecture with coprocessors, it has graphics and sound more advanced than most of its contemporaries. Video games were a major appeal, and first-person space combat simulator Star Raiders is considered the platform's killer app. The "Atari 8-bit family" label was not contemporaneous. Atari, Inc., used the term "Atari 800 [or 400] home computer system", often combining the model names into "Atari 400/800" or "Atari home computers".
Copy protection, also known as content protection, copy prevention and copy restriction, describes measures to enforce copyright by preventing the reproduction of software, films, music, and other media.
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.
A type-in program or type-in listing was computer source code printed in a home computer magazine or book. It was meant to be entered via the keyboard by the reader and then saved to cassette tape or floppy disk. The result was a usable game, utility, or application program.
The Commodore 64 amassed a large software library of nearly 10,000 commercial titles, covering most genres from games to business applications, and many others.
Creative Computing was one of the earliest magazines covering the microcomputer revolution. Published from October 1974 until December 1985, the magazine covered the spectrum of hobbyist/home/personal computing in a more accessible format than the rather technically oriented Byte.
A bit nibbler, or nibbler, is a computer software program designed to copy data from a floppy disk one bit at a time. It functions at a very low level directly interacting with the disk drive hardware to override a copy protection scheme that the floppy disk's data may be stored in. In most cases the nibbler software still analyses the data on a byte level, only looking to the bit level when dealing with synchronization marks (syncs), zero-gaps and other sector & track headers. When possible, nibblers will work with the low-level data encoding format used by the disk system, being Group Coded Recording, Frequency Modulation, or Modified Frequency Modulation.
A fast loader is a software program for a home computer, such as the Commodore 64 or ZX Spectrum, that accelerates the speed of file loading from floppy disk or compact cassette.
Amiga software is computer software engineered to run on the Amiga personal computer. Amiga software covers many applications, including productivity, digital art, games, commercial, freeware and hobbyist products. The market was active in the late 1980s and early 1990s but then dwindled. Most Amiga products were originally created directly for the Amiga computer, and were not ported from other platforms.
Home computers were a class of microcomputers that entered the market in 1977 and became common during the 1980s. They were marketed to consumers as affordable and accessible computers that, for the first time, were intended for the use of a single, non-technical user. These computers were a distinct market segment that typically cost much less than business, scientific, or engineering-oriented computers of the time, such as those running CP/M or the IBM PC, and were generally less powerful in terms of memory and expandability. However, a home computer often had better graphics and sound than contemporary business computers. Their most common uses were word processing, playing video games, and programming.
Karateka is a 1984 martial arts action game for the Apple II by Jordan Mechner. It is his first published game and was created while he was attending Yale University. The game was published in North America by Broderbund and in Europe by Ariolasoft. Along with Karate Champ and Yie-Ar Kung Fu, Karateka is one of the earliest martial arts fighting games. It was inspired by Japanese culture and by early Disney animated films and silent pictures.
Spiradisc was a copy protection scheme used by Sierra On-Line on their floppy disk releases for the Apple II. The technique, developed by Mark Duchaineau, involved writing the data on spiralling paths on the disk rather than in concentric circles. Initially, no commercial copying software or bit nibbler could successfully copy the disks it was applied to.
Where in Europe Is Carmen Sandiego? is a 1988 European geography-based educational computer game in the Carmen Sandiego detective mystery franchise. It was originally published by Broderbund in 1988 for Apple II, Commodore 64, and DOS, and ported to the Amiga and Macintosh in 1989. It is the third Carmen Sandiego title, after Where in the World Is Carmen Sandiego? (1985) and Where in the USA Is Carmen Sandiego? (1986). Under the guidance of The Acme Agency's chief, the player completes cases to catch Carmen's henchmen; they accomplish this by traveling to European cities to find clues relating to the crook's last known whereabouts, and by gaining enough character data to issue a warrant of arrest. Once the player has captured all 15 thieves, they can pursue Carmen herself.
ALF Products Inc., or ALF, was a Colorado company primarily known for its computer-controlled music synthesizers and floppy disk supplies and duplicators.
Donald's Alphabet Chase is a 1988 educational video game developed by Westwood Associates and published by Walt Disney Computer Software. It was released on various home computers including the Amiga, Amstrad CPC, Apple II, Commodore 64, DOS and ZX Spectrum. An Atari ST version was planned by Nathan Software but got no release. The game was released in five different languages including English, Spanish, French, Italian and German.
