Computer Chronicles

Computer Chronicles is an American half-hour television series, broadcast from 1983 to 2002 on Public Broadcasting Service (PBS) public television, which documented the rise of the personal computer from its infancy to the immense market at the turn of the 21st century. The series was created in 1983 by Stewart Cheifet (later the show's co-host), who was then the station manager of the College of San Mateo's KCSM-TV. The show was initially broadcast as a local weekly series. The show was co-produced by WITF-TV in Harrisburg, Pennsylvania. It became a national series on PBS from fall 1983. Jim Warren was the show's founding host for the 1981–1982 season. It aired continuously from 1981 to 2002, with Cheifet co-hosting most of the later seasons. Gary Kildall served as co-host from 1983 to 1990, providing insights and commentary on products, as well as discussions on the future of the ever-expanding personal computer sphere.

During the 1980s, the show had many supporting presenters, including:

Gary Kildall

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 was one of the first people to see microprocessors as fully capable computers rather than equipment controllers and to organize a company around this concept. He also co-hosted the PBS TV show The Computer Chronicles. Although his career in computing spanned more than two decades, he is mainly remembered in connection with IBM's unsuccessful attempt in 1980 to license CP/M for the IBM PC.

Early life

Gary Kildall was born and grew up in Seattle, Washington, where his family operated a seafaring school. His father, Joseph Kildall, was a captain of Norwegian heritage. His mother Emma was half-Swedish—Gary's grandmother was born in Långbäck, Sweden, in Skellefteå Municipality but emigrated to Canada at 23 years of age.

Gary attended the University of Washington (UW) hoping to become a mathematics teacher, but became increasingly interested in computer technology. After receiving his degree, he fulfilled a draft obligation to the United States Navy by teaching at the Naval Postgraduate School (NPS) in Monterey, California. Being within an hours' drive of Silicon Valley, Kildall heard about the first commercially available microprocessor, the Intel 4004. He bought one of the processors and began writing experimental programs for it. To learn more about the processors, he worked at Intel as a consultant on his days off.

Altair 8800

The MITS Altair 8800 is a microcomputer designed in 1975 based on the Intel 8080 CPU. Interest grew quickly after it was featured on the cover of the January 1975 issue (published in late November 1974) of Popular Electronics, and was sold by mail order through advertisements there, in Radio-Electronics, and in other hobbyist magazines. The designers hoped to sell a few hundred build-it-yourself kits to hobbyists, and were surprised when they sold thousands in the first month. The Altair also appealed to individuals and businesses that just wanted a computer and purchased the assembled version. The Altair is widely recognized as the spark that ignited the microcomputer revolution. The computer bus designed for the Altair was to become a de facto standard in the form of the S-100 bus, and the first programming language for the machine was Microsoft's founding product, Altair BASIC.

History

While serving at the Air Force Weapons Laboratory at Kirtland Air Force Base, Ed Roberts and Forrest M. Mims III decided to use their electronics background to produce small kits for model rocket hobbyists. In 1969, Roberts and Mims, along with Stan Cagle and Robert Zaller, founded Micro Instrumentation and Telemetry Systems (MITS) in Roberts' garage in Albuquerque, New Mexico, and started selling radio transmitters and instruments for model rockets.

Digital Research

Digital Research, Inc. (a.k.a. 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.
