Synapse

The historic electronic music magazine Synapse, now defunct, can be consulted and downloaded online.

For a nice online viewer, with indexes that jump straight to the articles, go to this page on Doug Lynner’s web site (Doug was one of the editors of Synapse)
For PDFs you can download of all except the very first two issues, go to this web page
For GIFs of individual pages of most of the magazines, visit the Wayback machine on the Internet Archive
