Small flexible plastic disk covered with a magnetic substance used to record data and computer programs. They can normally contain 1.44 MB of data and they are convenient for moving small amounts of data as they are transportable.
Intel’s first dual-core Itanium processor, code-named "Montecito" is a major release of Intel's Itanium 2 Processor Family, which implements the Intel Itanium architecture on a dual-core processor with two cores per die (integrated circuit). Itanium 2 is much more powerful than its predecessor. It has lower power consumption and thermal dissipation.
These are magnetic coil bands designed by IBM with 6250 BPI. BPI means bits per inch and specifies the data density a magnetic coil can hold.
This processor relies on two key points: maximum performance and minimum heat output. 4M Cache ; frequency 2.40 GHz ; 1066 MHz FSB
It's a timing disc from the CDC 3300 computer. This computer was released in 1965. Moreover CDC means Control Data Corporation.
System 7 is a single-user graphical user interface-based operating system for Macintosh computers and was part of the classic Mac OS line of operating systems. It was introduced on May 13, 1991, by Apple Computer. It succeeded System 6, and was the main Macintosh operating system until it was succeeded by Mac OS 8 in 1997. Features added with the System 7 release included virtual memory, personal file sharing, QuickTime, QuickDraw 3D, and an improved user interface. This is the first real major evolution of the Macintosh system, bringing a significant improvement in the user interface, improved stability and many new features such as the ability to use multiple applications at the same time. "System 7" is the last operating system name of the Macintosh that contains the word "system". Macintosh operating systems were later called "Mac OS" (for Macintosh Operating System).
This is a Weston AOIP standard battery with its calibration certificate (1956). Inside, the glassware forms an "H". Its name comes from the British physicist Edward Weston. A standard is the materialization of a given quantity whose value is known with great accuracy.
