Ibm Airline Control Program
IBM Airline Control Program, or ACP, is a discontinued operating system developed by IBM beginning about 1965. In contrast to previous airline transaction processing systems, the most notable aspect of ACP is that it was designed to run on most models of the IBM System/360 mainframe computer family. This departed from the earlier model in which each airline had a different, machine-specific transaction system. Overview Development began with ''SABRE (Semi-Automatic Business Research Environment)'', ''Deltamatic'', and ''PANAMAC''. From these, the ''Programmed Airline Reservations System (PARS)'' was developed. In 1969 the control program, ''ACP'', was separated from PARS. PARS kept the functions for processing airline reservations and related data. In December 1979, ACP became known as ACP/TPF and then just TPF (Transaction Processing Facility). The transaction operating system became more widely implemented by businesses other than the major airlines, such as online credit c ...

System/360
The IBM System/360 (S/360) is a family of mainframe computer systems that was announced by IBM on April 7, 1964, and delivered between 1965 and 1978. It was the first family of computers designed to cover both commercial and scientific applications and to cover a complete range of applications from small to large. The design distinguished between architecture and implementation, allowing IBM to release a suite of compatible designs at different prices. All but the only partially compatible Model 44 and the most expensive systems use microcode to implement the instruction set, which features 8-bit byte addressing and binary, decimal, and hexadecimal floating-point calculations. The System/360 family introduced IBM's Solid Logic Technology (SLT), which packed more transistors onto a circuit card, allowing more powerful but smaller computers to be built. The slowest System/360 model announced in 1964, the Model 30, could perform up to 34,500 instructions per second, with mem ...
