Unavailability of software and the associated source code can also be a hindrance for software archaeology and research. One of many examples is the closure of Atari in Sunnyvale, California in 1996, when the original source codes of several milestones of video game history (such as Asteroids and Centipede) were thrown out as trash, some of which were later recovered. Once a software product becomes abandonware, there is a high risk that the source code becomes lost or irrecoverable even for its original developers, as multiple cases have shown. If the software product is without alternative, the missing replacement availability becomes a challenge for continued software usage. If a software is distributed only in a digital, DRM-locked form or as SaaS, the shutdown of the servers will lead to a public loss of the software. These problems are exacerbated if software is bound to physical media with a limited life-expectancy ( floppy disks, optical media etc.) and backups are impossible because of copy protection or copyright law. compatibility fixes for newer hardware and operating systems. If a software product reaches end-of-life and becomes abandonware, users are confronted with several potential problems: missing purchase availability (besides used software) and missing technical support, e.g. Orphaned code The source code or executable might still be available but the author is unknown or only identified by a dead email or equivalent and there is no realistic prospect of finding the owner of the IP. The DOS-based PC-LISP still runs well within emulators and on Microsoft Windows. One such case is PC-LISP, still found online, which implements the Franz Lisp dialect. Unsupported or unmaintained shareware Open source and freeware programs that have been abandoned In some cases, source code remains available, which can prove a historical artifact. In some cases these sites had to remove past versions of software, particularly if the company producing that software still maintains it, or if later software releases introduce digital rights management, whereby old versions could be viewed as DRM circumvention. Some websites collect and offer for download old versions of shareware, freeware, and (in some cases) commercial applications. Authors may or may not make older releases available. Shareware whose author still makes it available Finding historical versions, however, can be difficult since most shareware archives remove past versions with the release of new versions. An example of this is Digital Research's original PL/I compiler for DOS: which was considered for many years as without an owner Micro Focus, which acquired Novell, which had bought Digital Research's assets, owns this old PL/I compiler, but has a more up-to-date PL/I offering. If the rights to a software are non-recoverable in legal limbo ("orphaned work"), the software's rights cannot be bought by another company, and there is no company to enforce the copyright. Commercial software owned by a company no longer in business When no owning entity of a software exists, all activities (support, distribution, IP activities etc.) in relationship to this software have ceased. Others, such as Microsoft, do not make old versions available for free use and do not permit people to copy the software. Some companies, such as Borland, make some software available online, in a form of freeware. In many cases, the company which owns the software rights may not be that which originated it, or may not recognize their ownership. Types Commercial software unsupported but still owned by a viable company The availability of the software depends on the company's attitude toward the software. Definitions of "abandoned" vary, but in general it is like any item that is abandoned – it is ignored by the owner, and as such product support and possibly copyright enforcement are also "abandoned". The term "abandonware" is broad, and encompasses many types of old software. Museums and various organizations dedicated to preserving this software continue to provide legal access. Within an intellectual rights contextual background, abandonware is a software (or hardware) sub-case of the general concept of orphan works. Look up -ware in Wiktionary, the free dictionary.Ībandonware is a product, typically software, ignored by its owner and manufacturer, and for which no official support is available.
