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 can not 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. 4 Arguments for and against distribution.
There was so much change in the 80’s and 90’s with DOS games and many seem to be all but forgotten, but we have them here! (If there is a game missing shoot us a message and we’ll put it up.) You will notice that many of the games will let you change sounds cards, graphics cards etc. These games were from a time when there were so many different types of PC's on the market that all had different hardware. There is just something magical about the old DOS games that just brings back memories and takes many of us back to our childhood or a time when things were simpler and just as much fun without all the animation that is the standard these days. ClassicReload was setup for preservation of 6,000+ old retro abandonware games and abandoned OS/interfaces that you can play DOS games online right in your web browser for education and research purposes.
