Sequential Circuits Prophet-5 Manual from 1979

images via this auction

"Written by Tom Darter in 1979, it's a loose leaf three ring binder with a clear vinyl cover. Contains patch sheets of all the factory presets, as well as several blank patch sheets, which is a bit odd considering that it was one of the first fully programmable synths. It says that this is Model 1000, so I don't know what Rev Prophet this is for. I assume it's one of the early ones."

Update via Micke in the comments: "The operation manual pictured is for the Rev 2 Prophet. Afaik, the first rev 2 shipped in May '79."
