Cromemco
Cromemco was a Mountain View, California microcomputer company known for its high-end Z80-based S-100 bus computers and peripherals in the early days of the personal computer revolution. The company began as a partnership in 1974 between Harry Garland and Roger Melen, two Stanford Ph.D. students. The company was named for their residence at Stanford University ( Crothers Memorial, a Stanford dormitory reserved for engineering graduate students). Cromemco was incorporated in 1976 and their first products were the Cromemco Cyclops digital camera, and the Cromemco Dazzler color graphics interface - both groundbreaking at the time - before they moved on to making computer systems. In December 1981, ''Inc.'' magazine named Cromemco in the top ten fastest-growing privately held companies in the U.S. Early history The collaboration that was to become Cromemco began in 1970 when Harry Garland and Roger Melen, graduate students at Stanford University, began working on a series of artic ...

Cromemco DOS
Cromemco DOS or CDOS (an abbreviation for Cromemco Disk Operating System) is a CP/M-like operating system by Cromemco designed to allow users of Cromemco microcomputer systems to create and manipulate disk files using symbolic names. Overview CDOS was written in Zilog Z80 machine code. Due to the number of available programs available to run under Digital Research CP/M at that time, CDOS was designed to be upwards CP/M-compatible. Many programs written for CP/M versions up to and including version 1.33 run without modification under CDOS. However, programs written for CDOS generally do not run under CP/M. The Cromemco Z-2 had the ability to run Cromemco DOS. Besides CP/M 2.2 and Cromix, the Cromemco System One can also run Cromemco DOS. The Cromemco C-10 personal computer, introduced in 1982, also ran CDOS. An emulator for a Cromemco CDOS system exists. Commands The following list of commands are supported by Cromemco DOS. Intrinsic commands * BYE * DIR * ERA * REN * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cromemco Z-2
Z-2 is a series of microcomputers made by Cromemco, Inc. which were introduced to the market in the middle to late 1970s. They were S-100 bus machines powered by the Zilog Z80 processor and typically ran on the CP/M operating system. They were originally available in assembled or kit form to serve both a commercial market and the computer enthusiast market. Later the machines were only available factory-assembled. The machines were widely respected for their speed, configurability, durability, and reliability. The Z-2 was a Z80–based microcomputer system that was introduced in 1977. The original Z-2 in kit form included a ZPU-K Z80 CPU card, S-100 bus motherboard, all-metal rack-mount chassis and dust case, card socket and card guide; the assembled form included a complete set of sockets and card guides, and a cooling fan. The Z-2 series was capable of supporting up to 21 S-100 boards and could be configured with any of the boards supplied by Cromemco. The Z-2 gave an impressi ...

Cromemco Bytesaver
The Bytesaver, introduced by Cromemco in 1976, was the first programmable memory board for the MITS Altair and S-100 bus microcomputer systems. The Bytesaver had sockets for 8 UV-erasable EPROMs providing up to 8 Kbytes of storage. The EPROMs could be programmed by the Bytesaver, or read as computer memory. In the history of microcomputer systems, the Bytesaver was the first viable alternative to the use of punched paper tape for storing programs, and has been called “a great advance in microcomputer technology”. Background The Altair 8800, which began the personal computer revolution, was introduced in January 1975 with no hardware or software support for floppy disk or hard disk storage. When Paul Allen travelled to the MITS factory in Albuquerque, New Mexico to demonstrate what would become Microsoft BASIC, he brought with him a punched paper tape of the code that he and Bill Gates had developed. According to Allen, the 7168 byte program took 7 minutes to load from a Telety ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cromemco Dazzler
The Cromemco Dazzler was a graphics card for S-100 bus computers introduced in a ''Popular Electronics'' cover story in 1976.Les Solomon"Solomon's Memory", in ''Digital Deli'', Workman Publications, 1984, It was the first color graphics card available for microcomputers.Harry Garland"Ten years and counting" ''Creative Computing'', Volume 10, Number 11 (November 1984), pg. 104 The Dazzler was the first of a succession of increasingly capable graphics products from Cromemco which, by 1984, were in use at 80% of all television stations in the U.S. for the display of weather, news, and sports graphics. History The Dazzler came about in a roundabout fashion after Les Solomon, Technical Editor for ''Popular Electronics'' magazine, demonstrated the original Altair 8800 to Roger Melen of Stanford University. After seeing it, Melen purchased Altair #2 for his friend Harry Garland to work with. The two built a number of add-ons for the machine, collaborating with Terry Walker on the desig ...

Harry Garland
Harry T. Garland (born 1947) is a scientist, engineer, author, and entrepreneur who co-founded Cromemco Inc., one of the earliest and most successful microcomputer companies. He received the B.A. degree in mathematics from Kalamazoo College, and the Ph.D. degree in biophysics from Stanford University. Dr. Garland has been recognized as one of the most important innovators in the development of personal computers in Silicon Valley. Personal life He is the son of Harry G. Garland, the founder of Garland Manufacturing. Stanford University Garland began his graduate work at Stanford University in 1968. Garland's research at Stanford focused on the function of the human brain in controlling voluntary movement. He developed techniques in electromyography for monitoring muscle activity during voluntary movement and worked to delineate the role of the brain and the role of local reflexes in the control of muscles. This led to a deeper understanding of brain function during voluntary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cromemco Cyclops
The Cromemco Cyclops, introduced in 1975 by Cromemco, was the first commercial all-digital camera using a digital metal-oxide-semiconductor (MOS) image sensor. It was also the first digital camera to be interfaced to a microcomputer. The digital sensor for the camera was a modified 1 kb dynamic RAM (DRAM) memory chip that offered a resolution of 32 × 32 pixels (0.001 megapixels). Background The Cyclops Camera was developed by Terry Walker, Harry Garland, and Roger Melen, and introduced as a hobbyist construction project in the February 1975 issue of '' Popular Electronics'' magazine. One month earlier the MITS Altair 8800 microcomputer had been introduced in this same magazine. Les Solomon, technical editor of Popular Electronics, saw the value of interfacing the Cyclops to the Altair, and put Roger Melen (co-developer of the Cyclops) in contact with Ed Roberts (president of MITS) to discuss a collaboration. Roger Melen met with Ed Roberts at MITS headqua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
