VAX-11/750. The VAX-11/750, code-named "Comet", is a more compact, lower-performance bipolar gate array–based implementation of the VAX architecture introduced in October 1980. [17] The use of gate arrays decreases power consumption, and increases reliability compared with the VAX-11/780. [18]

Apr 30, 2023 · The Digital Equipment Corporation (DEC) VAX-11/750 is a superminicomputer that was introduced in 1980. A number of computer history enthusiasts have collected, restored, and continue to operate these obsolete computers as a hobby.

VAX (an acronym for virtual address extension) is a series of computers featuring a 32-bit instruction set architecture (ISA) and virtual memory that was developed and sold by Digital Equipment Corporation (DEC) in the late 20th century.

The VAX-11/750 (also known as the VAX/750) is a slower, more compact, but less expensive successor to the initial VAX-11/780. It was primarily implemented in gate array chips holding 400 NAND gates ; they were configured at manufacture time into the …

Between 1977 and 2000, Digital Equipment Corporation (DEC) produced a wide range of computer systems under the VAX brand, all based on various implementations of the DEC-proprietary instruction set architecture of the same name.

With VAX, DEC extended its PDP-11 minicomputer architecture from 16 to 32 bits. The first model in the VAX “superminicomputer” line was the VAX-11/780. The line rivaled “much more expensive mainframe computers in performance,” according to the online Computer History Museum.

The VAX-11/750 Software Installation Guide presents step-by-step procedures for installing software on a VAX-11/750 processor. VAX-11/750 software installation falls into three general categories: This manual is intended for those users who managing and controlling the …

The VAX changed Digital's approach to architecture and became a standard of comparison for a new breed of superminicomputers. At the same time, the PC industry was launched by the Apple II,which could be hooked up to any color television.

Dec 8, 2014 · With only 400 gates to work with, the VAX architecture had to be divided over many arrays, it was still an improvements over discrete TTL which offers only a handful of gates per chip. In 1982 DEC released the VAX 11/730 Nebula, which was similar to the 750 but based on a commercial 4-bit slice processor (the 2901).

Internal and external shots of the VAX-11/750, with and without models. Photos include shots of the VAX-11/750 in production, thermal and power supply testing, and a hand inserting a cartridge.
