Miscellaneous related documentation

Some documentation can be hard to find, so here is a selection of documents that may be useful to enthusiasts.

Discontinued software
Good software that is no longer updated

Some companies have produced good software for OS/2, and then left the market. Occasionally, they have made the last version of the software freely available. Because this may eventually disappear from their web sites, and because on the whole it is worth preserving, some of it is being made available here. The repository includes software by Innoval (Post Road Mailer, J Street Mailer). There is also information on the independent, continued development of J Street Mailer, now known as the Polarbar Mailer.

There are also demonstration copies of the CDS products in the Backagain/2000 family.

There are fixes and updates for some software, notably ProNews/2, which is being actively developed once more by volunteers.

There is a copy of the Programming Tools and Information for OS/2 1.2/1.3. This is the equivalent to what is now known as the Toolkit.

Lastly, there is a repository of IBM Employee Written Software.
