ANALOG COMPUTERS
Our collection of over 50 analog computers is the largest known collection in the world. It contains some of the rarest, most unique analog computers known to exist.
These computers were critical in post-WWII era and were used by the military to develop the most advanced aircraft and artillery of the times and by NASA for their earliest space programs.
ANALOG COMPUTERS
Analog computers of the 1940s and 1950s played a pivotal role in laying the foundational concepts and methodologies that would shape our modern digital computing landscape.
These machines introduced the fundamental idea that complex mathematical problems could be solved by machines, demonstrating that machines could solve problems that had, until then, only been solved by humans educated in mathematics!
ANALOG SUPERPOWERS
This highly regarded review of international governmental theft, published on Oct. 2024, features a cover-image of one of the oldest analog computers in our collection.
The author, Dr. Epstein, traveled to The Computer Church so she could get a perfect image of the technology that is the focus of the book...the gears at the heart of the controversy.
ANALOG SUPERPOWERS
But this particular computer is very special for an entirely different reason!
This "Rangekeeper Mark VII" that is pictured was the fire-control computer for the big guns on the USS St. Louis, a light cruiser that was in Pearl Harbor for routine maintenance on the morning of December 7, 1941.
The St. Louis earned the nickname the "Lucky Lou" when it became the first ship to make it out of Pearl Harbor during the attack.

Homebrew Computer Club
This Newsletter stands as one of the most influential publications in the formation of Silicon Valley's technological culture and the personal computer revolution. Created and edited by its members, it initiated the idea of the personal computer and helped its members build early kit computers.
1975
Computer Notes
Computer Notes started as a company publication for MITS, but it became an important bridge between members of the emerging personal computer community. Among the key articles to appear was the 1976 publication of Bill Gates's famous "Open Letter to Hobbyists" which addressed intellectual property concerns in the new software industry.
1976
Hollerith Tabulating Machine
This is Hollerith personal copy of his
article about the Tabulating Machine.
Unique, this is the only known copy. The handwritten note at the top of the cover likely refers to drawings of the Tabulating Machine that were sent to the Franklin Institute (Phila.) regarding an award they were presenting to Hollerith.
1889
Nieman Marcus Catalog
Each year the famed Nieman Marcus store offers a Christmas Catalog that contains an outrageously expensive gift for a man and a woman. in 1969 they featured an expensive "Kitchen Computer". Mostly a publicity stunt, the computer included a cutting board and was advertised as useful place for storing recipes!
1969
Moore School Lectures
From July 8th through August 31st 1946, the University of Pennsylvania's Moore School of Electrical Engineering hosted 28 invited students to the world's first course on digital computers. Over six weeks, leading engineers and scientists discussed the experiences of the ENIAC and EDVAC.
1947
Time Magazine
Vannevar Bush's multifaceted contributions to computer development established him as a foundational figure in both the analog and digital computing eras. He was TIME Magazine's 1944 Man of the Year. And just a year later, his visionary essay As We May Think inspired generations of computer scientists.
1944
Electronics Magazine
This issue featured General Sarnoff on the cover (Head of RCA and an early proponent of TV) but is best known for an article by Gordon Moore about the increasing speed/power of computers. While Moore's Law is certainly aging, it still is valued by many in the computer industry.
1965
Punch Card Tabulation
This book by Leon Truesdell traces the development of Hollerith's punch card system from 1890 to 1940. This book is considered the definitive institutional account of the evolution from hand-written era of data collection within the U.S. Census Bureau.
