These are mostly 
PDF files, unless otherwise noted. File sizes are large, due to
grayscale 200 dpi scans for most items, which are better for accurate schematic
print-outs and zooming in to view assembly drawing sections, patch charts, etc. A few items are lower res scans that I have picked up from around the 'net over the years.
Simply clicking on the document links below should begin an automatic file download, probably to your default Downloads folder configured for your browser. Or you can always do the right-click>download-file-as option for other locations.
I've created a "Textbooks" section below for old EM texts in fear of being lost. Some textbooks will also appear within manufacturer docs if they are machine specific.

STD-1 Stereo Tapped Delay Owners Manual (13.8 MB)
I authored and illustrated this manual, after working on delay line prototyping and PCB development with Dave. This was such a fun device to work on. And, if you have one, you know how fun it is to use. The manual had 6 pages of blank patch charts, but I just scanned one of the blank charts.

ARP Sequencer Owners Manual (20.9 MB)
There are many copies of the Sequencer service manual around the net. But, in all my years of searching, I've never seen the Users Manual. So ... Here ya' go! This is a good introductory text on general sequencing theory and tricks, too!
ARP Sequencer Patch Chart [Homebrew] (464 KB)
ARP had a sequencer patch chart, in pad form, when the sequencer was first released. I have excerpted sections of the user manual illustrations, and generated a clean 8.5" X 11" (landscape orientation) patch chart as a PDF file. There are areas for patch name, date, and extra notes. The "Externals" column is meant to list external equipment I/O, and allow drawing lines from the patch chart up to the external item in the list, if desired.
ARP Sequencer Patch Chart [Original] (852 KB)
Finally! I've located a decent clean copy of the original Sequencer patch chart! Many thanks go out to Mark Chaplin in PA for this excellent find! Here is the original, as implemented by the folks at ARP. I like the staff under the tuning pots! Nice touch!

FM Theory and Applications, By Musicians for Musicians; by John Chowning and David Bristow, 1986 - PDF (18 MB)

This is a theory book, and doesn't contain patches or voice programming data. But plenty specific to be able to design FM voices in the FM synth of your choice based on the tutorials presented here.
