Our sincere thanks go to each contributor:
Leighton Greenough for his generous donation of the 11/20 and the related materials, for his subsequent descriptions and photos of FOSDIC history, and his suggestions about the contents of these Web pages. He corresponded with me in 2008 and provided the bulk of information about FOSDIC and the immediate history of the PDP-11/20. Thanks for his contributions, encouragments and good will.
David Gesswein for developing new videos of his PDP-8 and Teletype model 33 in operation. Those videos are used here and in the exhibit with his permission. He also loaned a PDP-11 card and paper tapes for the exhibit. David made considerable efforts to produce these videos and to discuss them Herb Johnson as part of this project.
Bill Degnan (MARCH board) for providing links to his 11/40 videos. Bill provided useful review for Herb as the project progressed.
Jeff Jonas provided review and discussion of the "minicomputer" poster, and contributed to its content.
Other persons who provided comments and suggestions include MARCH members Jack Rubin, Evan Koblenz, John Allain, and Jim Scheef.
Herb Johnson of retrotechnology.com. Herb developed these PDP 11/20 web pages and poster contents for the museum exhibit from August, 2007, thru September, 2008.
Jim Scheef (MARCH Webmaster) edited the pages for this website and added formatting.
