I don't know what a PGA puller is, but there is one at the Computer History Museum.

I guess Canada has so much universal healthcare that they just give away Mabis digital blood pressure monitors. Did you know that 45,000 Americans die each year due to lack of health insurance and more go bankrupt due to medical bills? USA! USA!
The Casio watch is dead. The motor was ripped from the heart of an evil robot. The power thingy too.
“Laboratory scientists challenge the MANIAC to a modified chess game.” MANIAC was an early computer built at Los Alamos.
In 1953, Shell Labs in Amsterdam was the first site in the Netherlands to use an electronic computer in a production environment. The computer was a Ferranti Mark I*, designed at Manchester University (with help from the legendary Alan Turing) and built by British company Ferranti. The Amsterdam model was called MIRACLE, for "Mokums (Amsterdam's) Industrial Research Automatic Calculator for Laboratory and Engineering", but some people nicknamed it "May It Replace All Chaotic Laboratory Experiments". My mother was one of its programmers and kept a photo album.
This was a monitor of the computer, that could only show binary digits; no characters. Below, a switchboard, used to input binary numbers by hand and set the start address of the program that was loaded from tape into the memory.
The memory was made of Williams-Kilburn tubes. The predecessor of this computer, the Baby, was the first to load its programs fully in memory before execution. Older computers needed to be rewired for each program change.

The Origins of the Internet
“When the Soviet Union launched the Sputnik satellite in 1957, the US government responded with dramatically increased support of technology research and development, much of it funded through the new Advanced Research Projects Agency (ARPA). In 1966 Bob Taylor of ARPA’s computer research division obtained funding for a network called ARPANET to link computers so that resources and results could be shared more easily. He hired Larry Roberts of MIT to manage the project, which was based on newly-invented packet-switching technology. At the end of the 1969 the ARPANET began operating with four nodes: University of California at Los Angeles and Santa Barbara, Stanford Research Institute, and University of Utah. That original ARPANET gradually grew into the Internet, which 30 years later had about 43 million nodes.
The early Internet, used primarily by engineers and scientists, was not at all user-friendly. As e-mail and file transfer protocols and programs matured, non-specialists started to use it. In 1989, Tim Berners-Lee of the CERN high-energy physics lab in Europe proposed a protocol for the exchange of online documents which became the basis for the World Wide Web. The development in 1993 of the graphical browser Mosaic by Marc Andreessen and his team at the National Center for Supercomputing Applications (NCSA) made the web accessible to everyone and led to its explosive growth. Marc Andreessen and entrepreneur Jim Clark founded Netscape in 1994 to create a web browser based on the Mosaic project. Netscape Navigator quickly dominated the early browser market.”

Cray-1, Cray Research Inc., 1976
“In 1972, computer designer Seymour Cray founded his own company, called Cray Research Inc., in his hometown of Chippewa Falls, Wisconsin. Working in seclusion for four years with a small group of people, Cray finally introduced his Cray-1 supercomputer in 1976. It was the fastest computer in the world at the time. The Cray-1’s unique physical design earned it the title of “the world’s most expensive loveseat,” a reference to the concentric bench that surrounds the main tower. Under this bench lies part of the machine’s power supply and air conditioning system while the computer’s overall circular shape allows wire lengths to be kept as short as possible, maximizing speed. Viewed from above, the “C” shape also alludes to the Cray name. The machine was wired completely by hand and used a Freon cooling system. Monthly operating cost, including service contract, was approximately $100,000.”

Millionaire Calculator, c. 1899
Hans W. Egli, Switzerland
“The Millionaire Calculator was invented in 1882 by Otto Steiger and built in Zurich by the firm of Hans W. Egil. While earlier machines required several turns of their calculating handle to multiply, the Millionaire could multiply a number by a single digit with only one turn. Its mechanism was a series of brass rods of various lengths that executed functions based on the same concept as Napier’s bones. Approximately 4700 Millionaires were manufactured between 1899 and 1935.”

Cray-2, Cray Research Inc., 1985
Memory: 512M (64-bit) Semi
Speed: 488 MFLOPS/CPU
Cost: $12-20,000,000
“Although smaller than the Cray-1, the Cray-2 could perform operations 12 times faster than its predecessor. The system was cooled by immersing its circuit boards in a liquid called Fluorinert. While most machines included up to four processors, this is the only eight-processor Cray-2 ever made. Twenty-seven Cray-2 computers were sold in all.”

According to the Baylor University press release from 10/8/1974, that accompanied this photo, it reads: "Checking a print-out from a new Systems III computer recently installed in Baylor University's Hankamer School of Business are (left to right) Mrs. Helen Ligon, Baylor associate professor of statistics; Louis Pisaturo, a graduate student in business administration from Providence, R.I.; and Loren Decker, an instructor in statistics and director of the business school's Casey Computer Center. The new computer is faster, smaller, and easier to operate than other computers, and it should prove a valuable learning tool for Baylor business students."
