Applied Logic Corporation
Applied Logic Corporation (AL/COM) was a time-sharing company in the 1960s and 70s. Headquartered in Princeton, New Jersey, AL/COM started in 1962 working on "mathematical techniques and their applications to problem-solving." Seeing the need for in-house time sharing the company bought a Digital Equipment Corporation (DEC) PDP-6 and developed its time sharing service, which came on-line in 1966. In 1968 the company began development of "Mathematics Park" in Montgomery Township, New Jersey, "designed to provide tenants with a computer-serviced and mathematically-oriented environment," adjacent to the Princeton Airport (New Jersey), Princeton Airport. Also in 1968 the company registered ''AL/COM'' as a trademark for its service. The system involved both custom software and custom hardware, and the service was marketed nationally by a network of associates. In the late 1960s, the company developed a system called SAM (Semi-Automated Mathematics) for proving mathematical theories ...

Time-sharing
In computing, time-sharing is the Concurrency (computer science), concurrent sharing of a computing resource among many tasks or users by giving each Process (computing), task or User (computing), user a small slice of CPU time, processing time. This quick switch between tasks or users gives the illusion of Parallel computing, simultaneous execution. It enables computer multitasking, multi-tasking by a single user or enables multiple-user sessions. Developed during the 1960s, its emergence as the prominent model of computing in the 1970s represented a major technological shift in the history of computing. By allowing many users to interact concurrent computing, concurrently with a single computer, time-sharing dramatically lowered the cost of providing computing capability, made it possible for individuals and organizations to use a computer without owning one, and promoted the Interactive computing, interactive use of computers and the development of new interactive application ...

Leaseback
Leaseback, short for "sale-and-leaseback", is a financial transaction in which one sells an asset and leases it back for the long term; therefore, one continues to be able to use the asset but no longer owns it. The transaction is generally done for fixed assets, notably real estate, as well as for durable and capital goods such as airplanes and trains. The concept can also be applied by national governments to territorial assets; prior to the Falklands War, the government of the United Kingdom proposed a leaseback arrangement whereby the Falklands Islands would be transferred to Argentina, with a 99-year leaseback period, and a similar arrangement, also for 99 years, had been in place prior to the handover of Hong Kong to mainland China. Leaseback arrangements are usually employed because they confer financing, accounting or taxation benefits. Leaseback arrangements After purchasing an asset, the owner enters a long-term agreement by which the property is leased back to the sell ...

Computer Companies Disestablished In 1975
A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (''computation''). Modern digital electronic computers can perform generic sets of operations known as ''programs'', which enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster. A broad range of industrial and consumer products use computers as control systems, including simple special-purpose devices like microwave ovens and remote controls, and factory devices like industrial robots. Computers are at the core of general-purpose devices such as personal computers and mobile devices such as smartphones. Computers power the Internet, which links billions of computers ...
