1. The Bluegrass website where you can email them about buying their developer (which they say does not contain Glycine and is definitly not the same as Ed Buffaloe's 777.
2. The Unblinking Eye site where you can read the article "Remembering 777" by Fred De Van with additional comments by Ted Kaufman, Larry Price and Ed Buffaloe. This article contains the formula for Ed Buffaloe's 777.
