Grace Hopper
"Rear Admiral Grace Murray Hopper (December 9, 1906 – January 1, 1992) was an American computer scientist and United States Naval officer. A pioneer in the field, she was one of the first programmers of the Harvard Mark I computer, and she developed the first compiler for a computer programming language."

This is a PC Magazine journalist, Mark Hachman, taking a picture of the Apple I inside the new 25,000-square-foot "Revolutions" exhibit at the Computer History Museum.
This is the second out of four Canon Cat promotional photos that I had access to, scanned and cleaned up.
Here is the description accompanying the photo:
Canon Cat “work processor” combines functions of several office machines into one compact, easy system, including typing, word processing, information storage and retrieval, calculating and communicating with other Cats or computers. Engineered and produced from a concept of Jef Raskin, originator of the Macintosh computer. The Cat has two "Leap" keys, with which text can easily be edited, moved, restyled, underlined, boldfaced and even checked for spelling. Suggested list price is $1,495.

In October 2007 Chuck and I visited the Computer History Museum in Mountain View, CA. Stan Sieler gave us a tour and here is your chance to come along.

The magnetic tape drive shown here is part of the IBM 1401 Data Processing System.
The magnetic tape drive was one of the storage technologies that succeeded punch cards in computer history. It allowed for greater data density and off site storage, however it was too fragile for long term archival of information. It also, like other digital storage mediums, required a machine to enable the user to access the stored information.

SAGE, USAF/IBM, c. 1954
Memory: magnetic core 69,632 (33-bit) words
Speed: 80,000 Add/s
Cost: $8-12 billion (entire system)
“SAGE (Semi-Automatic Ground Environment) was a large computerized air defense system built in response to the Cold War threat of Soviet bombers. By analyzing radar data in real-time, SAGE provided the Air Force with a picture of the North American airspace and could relay targeting information to fighter planes. In practice, it is doubtful that SAGE could have effectively responded to an invasion. IBM built SAGE hardware based on the Whirlwind computer design at MIT. The many technical advances include modems for communication between sites over telephone lines, networking, light guns, graphical displays, and reliable magnetic core memory.
Each of the 27 SAGE installations had two separate computers, the second serving as a “hot standby” in case the active computer failed. With this backup, availability was unprecedented 99.6%, when many other computers from that era would fail every few hours. The computer weighed 300 tons and typically occupied one floor of a huge windowless 4-story concrete blockhouse. On another floor, dozens of Air Force operators watched their display screens and waited for signs of enemy activity.
The software was written by The Rand Corporation and the System Development Corporation (SDC) and employed about 20% of the world’s programmers at the peak of the project. When it was complete, the 250,000 lines of code was the most complex piece of software in existence. Some SAGE centers continued to operate until 1983, more than 20 years after its technology was obsolete and its mission rendered militarily insignificant by the ICBM. As a final irony, in the last years of its use, replacement vacuum tubes had to be purchased from Soviet-bloc countries where they were still widely being manufactured.”

A teletype keyboard attached to the Zuse 23 computer.
A very interesting layout, with German QWERTZ and an integrated keypad.
A small arcade, part of the videogames exhibition in Museum Of The Moving Image in New York City.
There was a bigger arcade on the lower level too, with newer titles.
