Digital Research

Digital Research, Inc. (aka DR or DRI; originally Intergalactic Digital Research) was the company created by Dr. Gary Kildall to market and develop his CP/M operating system and related products. It was the first large software company in the microcomputer world. Digital Research was based in Pacific Grove, California.

The company's operating systems, starting with CP/M for 8080/Z80-based microcomputers, were the de facto standard of their era, as MS-DOS and MS Windows came later. DR's product suite included the original CP/M and its various offshoots; DR-DOS which was a MS-DOS compatible version of CP/M, and MP/M, the multi-user CP/M. The first 16-bit system was CP/M-86, which was to be unsuccessful in competition with MS-DOS. There followed Concurrent CP/M, a single-user version of the multi-tasking MP/M-86 featuring "virtual consoles" from which applications could be launched to run concurrently. Successive revisions of this system, which gradually supported MS-DOS applications and the FAT filesystem, were labelled Concurrent DOS, Concurrent DOS XM and Concurrent DOS 386.

In 1985, soon after the introduction of the Intel 80286, Digital Research introduced a real-time system, initially called Concurrent DOS 286 and subsequently FlexOS. This exploited the greater memory addressing capability of the new CPU to provide a more flexible multi-tasking environment. There was a small but powerful set of system APIs, each with a synchronous and an asynchronous variant. Pipes were supported, and all named resources could be aliased by setting Environment variables. This system was to enjoy enduring favour in point-of-sale systems and was adopted by the IBM 4690 OS.

Digital Research was purchased by Novell in 1991, primarily for Novell to gain access to the operating system line.

DR produced a selection of programming language compilers and interpreters for their OS-supported platforms, including C, Pascal, COBOL, Forth, PL/I, PL/M, BASIC, and Logo. They also produced a microcomputer version of the GKS graphics standard (related to NAPLPS) called GSX, and later used this as the basis of their GEM GUI. Less known are their application programs, limited largely to the GSX-based DR DRAW, Dr. Halo for DOS and a small suite of GUI programs for GEM.

    It is a good morning exercise for a research scientist to discard a pet hypothesis every day before breakfast. It keeps him young.
