	The IBM 7094 and CTSS
		MIT got an IBM 7090, replacing the 709, in the spring of 1962, when I was a freshman, and had upgraded the 7090 to a 7094 by 1963.
		One use IBM made of it was yacht handicapping: the president of IBM raced big yachts on Long Island Sound, and these boats were assigned handicap points by a complicated formula.
		The 7094 was a fine machine, but by the time it was over ten years old, it had become expensive to maintain, hard to find expert programmers for, and had been deserted by most users in favor of faster and more modern machines.

	IBM 7090 - Wikipedia, the free encyclopedia
		The IBM 7090 was a second-generation transistorized version of the earlier IBM 709 vacuum tube mainframe computers and was designed for "large-scale scientific and technological applications".
		The 7094 introduced double-precision floating point and additional instructions, but was largely backward compatible with the 7090.
		In April 1964, the first 7094 II was installed, which had almost twice as much general speed as the 7090 due to a faster clock cycle and introduction of overlapped instruction execution.

	IBM 7302 - Wikipedia, the free encyclopedia
		The IBM 7094 II used one IBM 7302, but it was a new model unique to the IBM 7094 II.
		The core memory in the IBM 7302 was heated/cooled to stabilize its operating characteristics.
		The use of smaller cores in the IBM 7302A allowed the cycle time to be reduced to 2.0µs for the IBM 7094.

		MISTRAM was a tracking system that was used on a number of projects (including Apollo) and the Air Force required a data-collection computer to be installed in a tracking station downrange from Cape Canaveral.
		The data would eventually be shared with the 36-bit IBM 7094 machine at the Cape, so the computer would likely have to be 36-bits as well (why they didn't use an IBM 7094 is something of a mystery).
		However by the early 1960s GE was the largest user of IBM mainframes, and purchasing their own machines seemed like an excellent way to lower the costs of their computing department.

	IBM PC from FOLDOC
		IBM PCs and compatible models from other vendors are the most widely used computer systems in the world.
		Note: "IBM PC" is used in this dictionary to denote IBM and compatible personal computers, and to distinguish these from other personal computers, though the phrase "PC" is often used elsewhere, by those who know no better, to mean "IBM PC or compatible".
		When a new peripheral device, such as a monitor or scanner, is added to an IBM compatible, a corresponding, new controller board must be plugged into an expansion slot (in the bus) in order to electronically control its operation.
