Pyramid Technology (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Pyramid Technology Corporation was a computer company that produced a number of RISC-based minicomputers at the upper end of the performance range. They also became the second company to ship a multiprocessor Unix system, in 1985, which formed the basis of their product line into the early 1990s. Pyramid's OS/x was a dual-universe Unix which supported programs and system calls from both 4.xBSD and AT&T's System V Unix. In 1995 Pyramid was bought by Siemens AG and merged into their Siemens Computer Systems US unit. In 1998 this unit was split, with the services side of the operation becoming Wincor Nixdorf. In 1999 Siemens and Fujitsu merged their computer operations to form Fujitsu Siemens Computers, and finally Amdahl was added to the mix in 2000.
