The Museum of HP Calculators

The Museum of HP Calculators – Everything you want to know about the history and technical information of HP calculators.

David G. Hicks is the curator of this great collection of HP pocket and early desktop calculators. His web site is a reference for all HP collectors.

The Kenneth Kuhn HP Museum

Ken Kuhn's HP Museum web site. This is an extensive and beautiful collection of vintage HP instruments, owned by professor Kenneth Kuhn of the University of Alabama, Birmingham, Alabama. An in-depth reading of the many chapters of Ken's Web Site will reveal how the HP Way can be a personal and work resource even for people who never worked at HP.

It is intriguing that Professor Kuhn never worked for HP, yet had admired the company and its products for decades. His day job is an instrument designer for a measurements company, so he appreciates the sophistication of creative product strategies, and the execution of reliable and high-performance instruments.

His instrument collection itself, is in the hundreds. He is quite an expert on the nuances of different serial numbers of early HP 200-series oscillators.

The HP Computer Museum

Probably the most complete collection of HP computers worldwide, the museum resides in Melbourne, Australia and is managed by Jon Johnston.

In addition to the very accurate listing of HP's computer production, the Web Site offers a download service containing a huge quantity of original HP software.
Boot disks and utilities for most of the early HP computers can be found and downloaded from the "Resources", "Software" chapter of the Web Site. A great contribution to the HP, computer collectors, community.

HP9825.COM "The Story of the Little Computer That Could!"

Fully dedicated to the story of the 9825 desktop computer, this site is managed by Steve Leibson.
Not a museum, this site is rather a book telling the story of the computer's life from its birth to the 9825 introduction. The site is a huge source of information on the first decade of HP computer evolution. It is a very pleasant reading about early computing technology and the men who did it.

The HP 9825 computer was the third generation of desktops from HP. The HP 9100 was the first scientific desktop, featuring a 16-layer printed circuit board and 2400 discrete diodes which served as the ROM. This was before the era of the integrated circuits. It popularized Reverse Polish Notation for the display and operator functions.

The HP 9810/20/30 computers (second generation) followed, which DID have full integrated circuit complements, GPIB Interface Bus, and other peripherals.

The Vintage Hewlett Packard Archive

This is a growing documentation site that is being hosted by Glenn Robb, who is an ElectroMagnetic Compatibility Engineer.
Glenn provides the HP collector community with many contributions, including tens of thousands of pages of catalogs, periodicals, and service information... even a scan of the very first HP catalog -- a very rare item which was published in 1943.
Glenn coordinates the efforts of many "scanning volunteers", and is always looking for more help!

The LeapSecond Web Site

A web site dedicated to precise Time & Frequency.

Tom Van Baak is the curator of this Web Site on which he shows his "one man's quest for the most accurate clock " and the way to follow to reach that target.

Tom's collection of Hewlett Packard Clocks and Frequency Standards spans the fifty years of the HP's leadership on the Time and Frequency Measurement Technology Market.

The HP Series 80 Web Site

A large collection and a nice web site fully dedicated to the HP 80 Series Computer.

Vassilis Prevelakis, who is the curator, wish to gather all the material that is still available for the Series 80 and post them on this site, so that people who wish to use these venerable machines can use this site as a resource.

The HP 9845 Project Web Site

Managed by Ansgar Kueckes, the HP 9845 Project Web Site is dedicated to all those who share the fascination for one of the first workstations ever, the HP 9845 desktop computer.

This site tries to preserve and provide as much knowledge as possible around the HP 9845 series.
An in-depth and highly professional work about this very special system which was the first that could justifiably be called a "Workstation".

The Jacques Laporte Web Site

This is an excellent site pertaining to the HP35 calculator. 

It contains details of the algorithms and a lot of other information all in one convenient place.  Information on other HP calculators is coming.

The Hans Kulk Web Site

Hans Kulk Web Site

Hans Kulk has a nice collection of analog equipment for his electronic experiments. Mostly made of HP instruments the main objective of the Hans' lab is to freely experiment and to research sounds and control with this particular equipment.

Hans's Web Site is under complete reconstruction. Link to it will be reactivated at restart.
