The Ampex “Fact Book”
Other contemporary publications
The 2001 December Hammar group was about half transcribed, also by Chuck Booye
two interviews served as the basis of a written history. The history
was be prepared by John Leslie in collaboration with the late Ross
Snyder, based on the transcriptions and other resources. Jay McKnight and Bill Wray provided editorial services
Larry Miller will attempt to produce a “rectified” Time Line Excel spread sheet to aid in reconciling detail differences.
Larry Miller will also write an addendum to the Leslie paper which details the operations at Ampex Audio in Sunnyvale. (Ampex Professional Audio was relocated to Sunnyvale in about 1961 to take advantage of the large common parts inventory and manufacturing methods used in both professional and early consumer product lines.)
