Is Cray one a supercomputer?
development by Cray Research Inc. His company’s first supercomputer, the Cray-1, which came out in 1976, could perform 240 million calculations per second. It was used for large-scale scientific applications, such as simulating complex physical phenomena, and was sold to government and university laboratories.
Are VAX computers still in use?
In August 2000, Compaq announced that the remaining VAX models would be discontinued by the end of the year, but old systems remain in widespread use. The Stromasys CHARON-VAX and SIMH software-based VAX emulators remain available.
What happened to DEC VAX?

What happened to DEC Alpha?
Compaq, already an Intel x86 customer, announced that they would phase out Alpha in favor of the forthcoming Hewlett-Packard/Intel Itanium architecture, and sold all Alpha intellectual property to Intel, in 2001, effectively killing the product.

What influenced the design of the PDP-11 operating system?
The design of the PDP-11 inspired the design of late-1970s microprocessors including the Intel x86 and the Motorola 68000. Design features of PDP-11 operating systems, as well as other operating systems from Digital Equipment, influenced the design of other operating systems such as CP/M and hence also MS-DOS.
What are the input and output instructions of the PDP-11?
There are no specific input or output instructions; the PDP-11 uses memory-mapped I/O and so the same move instruction is used; orthogonality even enables moving data directly from an input device to an output device. More complex instructions such as add likewise can have memory, register, input, or output as source or destination.
