The SDA Handbook is now available in a downloadable PDF format. The Handbook has all the content of the SDA Compendium except for my personal commentary and (outdated) descriptions of my SDA-based rigs. The SDA Handbook runs 106 pages compared to the Compendium's 127.
The SDA Compendium is out of print.
The Handbook exceeds the 2MB limit that I can upload. I have emailed the document to Patrick and asked him to attach it and make this thread a sticky.
