Online Museum and Technical History of Hewlett-Packard (now Agilent Technologies)

This web site is devoted to the history of test equipment produced by the Hewlett-Packard Company which is now known as Agilent Technologies. I own a huge collection of vintage Hewlett-Packard test equipment, catalogs, equipment manuals, and Hewlett-Packard Journals. I own such classics as the HP200A, HP200B, HP200C, HP200D, HP200H, HP201B, HP202D, HP410A, HP500A, and many more (a rough count indicated over 450 pieces of which about 100 are duplicates). I also own probably one of the few still existing HP210A square wave generators.
