NCR 200 wasn't the first NCR computer at Panama Canal.
Now I have (thanks to Ian Ormerod) materials saying that the first computer at Panama Canal was NCR 315. It was officially opened for operation on June 21, 1965 at Data Processing Center in the Balboa Heights Administration Building. Inauguration ceremony has been opened by Canal Zone Governor Robert J. Fleming Jr.
The computer controlled inventory on merchandise ordered by the Panama Canal retail stores from the warehouse and regulated orders from the warehouse to outside vendors.
I will prepare these materials for publishing and post them to the site.
I was trained on the 315 (in Dayton in 1965 and 1966) and there were two guys in my class from Panama.
