But you can find the source code online thanks to the http://snapshot.debian.org/ service from Debian.
- Versions of pcsc-lite from 1.0.2.beta5-1 (2005-03-12) are here.
- Version of libccid from 0.9.2-2 (2005-03-12) are here.
It is also possible to use tagged version from the subversion repository. But you will not get a .tar.gz archive, just the source code files.
You may note that the versions from subversion do not go back as far as from http://snapshot.debian.org/. This is because, at the origin, the code was managed in CVS (not subversion) and not all the versions have been tagged (AFAIR).
