Hi Bob,A great connection eednid! I'd be interested in hearing more about your experiences working on GRIPHOS. Most of the early materials from David Vance's presidency are now housed at the Smithsonian Institute Archives and some of your recollections could be a nice addition to the paper records that are there. I stumbled across this copy of the manual through an online bookstore. As you can see in this , it's stamped with James H. Baker on the front. Any idea who he might be? I also have a copy of the 1968 Met conference that includes Carl Dautermann's Sevres work, and a somewhat incomplete run of Spectra from the mid 70s.
