I've joined the ASMA team to update the website, which has been dormant and without updates for quite some years. The website has been completely restructured and updated and now offers a powerful search, an up-to-date SAP player in your browser, and exports of SAP files to different formats. More features and improvements are added continuously.
Visit http://asma.atari.org/ and dig into the sounds of the Atari and join the AtariAge thread to receive detailed updates, post your songs for the archive, or report issues.
