Digital Equipment Corporation should not be confused with the unrelated companies Digital Research, Inc or Western Digital ( despite the latter manufacturing the LSI-11 chipsets used in DEC's low end PDP-11 / 03 computers ).

Digital Research produced a compatible variant known as DR DOS, which was eventually taken over ( after a buyout of Digital Research ) by Novell, then by Caldera.

Gary Arlen Kildall ( May 19, 1942 – July 11, 1994 ) was an American computer scientist and microcomputer entrepreneur who created the CP / M operating system and founded Digital Research, Inc. ( DRI ).

Kildall and his wife Dorothy established a company, originally called " Intergalactic Digital Research " ( later renamed as Digital Research, Inc ), to market CP / M through advertisements in hobbyist magazines.

Digital Research licensed CP / M for the IMSAI 8080, a popular clone of the Altair 8800.

IBM approached Digital Research in 1980, at Bill Gates ' suggestion, to negotiate the purchase of a forthcoming version of CP / M called CP / M-86 for the IBM PC.

In January 1985, Digital Research previewed the Concurrent DOS 286 operating system made in cooperation with Intel.

This worked on the B-1 prototype step of the chip, but Digital Research discovered problems with the emulation on the production level C-1 step in May, which would not allow Concurrent DOS 286 to run 8086 software in protected mode.

In August, after extensive testing E-1 step samples of the 80286, Digital Research acknowledged that Intel corrected all documented 286 errata, but said there were still undocumented chip performance problems with the prerelease version of Concurrent DOS 286 running on the E-1 step.

Intel said the approach Digital Research wished to take in emulating 8086 software in protected mode differed from the original specifications.

Nevertheless, they implemented minor changes in the microcode that would allow Digital Research to run emulation mode much faster, incorporated into the E-2 step.

ATM was developed to meet the needs of the Broadband Integrated Services Digital Network, as defined in the late 1980s.

With the development of the internet, by the late 1990s and early 2000, much of that regulation had been replaced where newer industry technologies developed, offering viewers alternate choices for local events and programming leading to what is today, that being Digital Cable, Internet, and Phone being offered to consumers, bundled, by 2010.

Digital television ( including higher quality HDTV ) started to spread in most developed countries in early 2000s.

DPNSS was developed in the early 1980s by BT, or its forerunner, Post Office Telecommunications in recognition that the emerging Digital Private Circuit Primary Rate product ' Megastream ' had to address the market for both data and voice, the latter being significantly greater because of the market for PBXs.

Alpha, originally known as Alpha AXP, is a 64-bit reduced instruction set computer ( RISC ) instruction set architecture ( ISA ) developed by Digital Equipment Corporation ( DEC ), designed to replace the 32-bit VAX complex instruction set computer ( CISC ) ISA and its implementations.

The same limitations affected Digital Research's FlexOS 286 version 1. 0, a derivation of Concurrent DOS 286, developed in 1986, introduced in January 1987, and later adopted by IBM for their IBM 4690 OS.

The method was developed to replace the Plesiochronous Digital Hierarchy ( PDH ) system for transporting large amounts of telephone calls and data traffic over the same fiber without synchronization problems.

The IS-IS protocol was developed by Digital Equipment Corporation as part of DECnet Phase V. It was standardized by the ISO in 1992 as ISO 10589 for communication between network devices which are termed Intermediate Systems ( as opposed to end systems or hosts ) by the ISO.

Originally developed as the " Dartmouth Digital Synthesizer " by Dartmouth College Professor Jon Appleton, in association with NED co-founders Cameron W. Jones and Sydney A. Alonso, the Synclavier would become the pioneering prototype hardware and software system for all digital non-linear synthesis, polyphonic sampling, magnetic ( hard-disk ) recording and sequencing systems technology that is commonplace in all music and sound effects / design today.

Employees at Bellcore ( now Telcordia Technologies ) developed Asymmetric Digital Subscriber Line ( ADSL ) and filed a patent in 1988, by placing wide-band digital signals above the existing baseband analog voice signal carried between telephone company telephone exchanges and customers on conventional twisted pair cabling facilities.

Design features of the PDP-11 influenced the design of microprocessors such as the Motorola 68000 ; design features of its 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.

CP / M ( Control Program / Monitor ) was a mass-market operating system created for Intel 8080 / 85 based microcomputers by Gary Kildall of Digital Research, Inc.

The only hardware system that CP / M, as sold by Digital Research, would support was the Intel 8080 Development System.

While the Digital Research distributed core of CP / M ( BDOS, CCP, core transient commands ) did not use any of the Z80-specific instructions, many Z80 based systems used Z80 code in the system specific BIOS, and many applications were dedicated to Z80 based CP / M machines.

The established small system operating software was CP / M from Digital Research which was in use both at the hobbyist level and by the more professional of those using microcomputers.

The most important of the early OSes on these machines was Digital Research's CP / M-80 for the 8080 / 8085 / Z-80 CPUs.

Similar 8. 3 file naming schemes have also existed on earlier CP / M, Atari, and some Data General and Digital Equipment Corporation minicomputer operating systems.

It was originally developed by Gary Kildall's Digital Research and derived from Concurrent PC DOS 6. 0, which was an advanced successor of CP / M-86.

Digital Research's original CP / M for the 8-bit Intel 8080 and Z-80 based systems spawned numerous spin-off versions, most notably CP / M-86 for the Intel 8086 / 8088 family of processors.

IBM originally approached Digital Research, seeking an x86 version of CP / M.

Digital Research threatened legal action, claiming PC DOS / MS-DOS to be too similar to CP / M.

The proportion of PC buyers prepared to spend six times as much to buy CP / M-86 was very small, and the availability of compatible application software, at first decisively in Digital Research's favor, was only temporary.

Digital Research fought a long losing battle to promote CP / M-86 and its multi-tasking multi-user successor Concurrent CP / M-86, and eventually decided that they could not beat the Microsoft-IBM lead in application software availability, so they modified Concurrent CP / M-86 to allow it to run the same applications as MS-DOS and PC DOS.
