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
Cromemco was a Mountain View, California microcomputer company known for its high-end Zilog Z80, 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 (George E. Crothers, 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), ''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 ...

Emulator
In computing, an emulator is Computer hardware, hardware or software that enables one computer system (called the ''host'') to behave like another computer system (called the ''guest''). An emulator typically enables the host system to run software or use peripheral devices designed for the guest system. Emulation refers to the ability of a computer program in an electronic device to emulate (or imitate) another program or device. Many Printer (computing), printers, for example, are designed to emulate Hewlett-Packard, HP LaserJet printers because so much software is written for HP printers. If a non-HP printer emulates an HP printer, any software written for a real HP printer will also run in the non-HP printer emulation and produce equivalent printing. Since at least the 1990s, many video game enthusiasts and hobbyists have used emulators to play classic arcade games from the 1980s using the games' original 1980s machine code and data, which is interpreted by a current-era s ...

Roger Melen
Roger Douglas Melen (born 1946) is an electrical engineer recognized for his early contributions to the microcomputer industry, and for his technical innovations. Dr. Melen was co-founder of Cromemco, one of the earliest microcomputer companies. At Cromemco he developed color graphics systems that were widely used in television broadcast, and in mission planning systems deployed by the United States Air Force. He also developed the first microcomputer systems widely distributed in China. In addition to his work in microcomputer systems and color graphics, Dr. Melen has made significant technical contributions to the development of CCD image sensors, ultrasonic imaging systems, implantable cochlear devices, image processing technology, and vehicular information systems. He has been recognized as one of the most important inventors and innovators in the history of Silicon Valley. Early contributions As a young man, Roger Melen enjoyed ham radio, operating an amateur radio station ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ATTR (CP/M Command)
Amyloidosis is a group of diseases in which abnormal proteins, known as amyloid fibrils, build up in tissue. There are several non-specific and vague signs and symptoms associated with amyloidosis. These include fatigue, peripheral edema, weight loss, shortness of breath, palpitations, and feeling faint with standing. In AL amyloidosis, specific indicators can include enlargement of the tongue and periorbital purpura. In wild-type ATTR amyloidosis, non-cardiac symptoms include: bilateral carpal tunnel syndrome, lumbar spinal stenosis, biceps tendon rupture, small fiber neuropathy, and autonomic dysfunction. There are about 36 different types of amyloidosis, each due to a specific protein misfolding. Within these 36 proteins, 19 are grouped into localized forms, 14 are grouped as systemic forms, and 3 proteins can identify as either. These proteins can become irregular due to genetic effects, as well as through acquired environmental factors. The four most common types of sys ...

TYPE (CP/M Command)
In computing, is a command in various command-line interpreters ( shells) such as COMMAND.COM, cmd.exe, 4DOS/ 4NT and Windows PowerShell used to display the contents of specified files on the computer terminal.

REN (CP/M Command)
In computing, ren (or rename) is a command in various command-line interpreters ( shells) such as COMMAND.COM, cmd.exe, 4DOS, 4NT and Windows PowerShell. It is used to rename computer files and in some implementations (such as AmigaDOS) also directories. It is analogous to the Unix mv command. However, unlike mv, ren cannot be used to move files, as a new directory for the destination file may not be used. Alternatively, move may be used if available. On versions of MS-DOS that do not support the move command (older than 6.00), the user would simply copy the file to a new destination, and then delete the original file. A notable exception to this rule is DOSBox, in which ren may be used to move a file, since move is not supported. Implementations The command is available in the operating systems Digital Research CP/M, MP/M, Cromemco CDOS, MetaComCo TRIPOS, DOS, IBM OS/2, Microsoft Windows, ReactOS, SymbOS, and DexOS. Multics includes a rename command to rename a directory en ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ERA (CP/M Command)
An era is a span of time defined for the purposes of chronology or historiography, as in the regnal eras in the history of a given monarchy, a calendar era used for a given calendar, or the geological eras defined for the history of Earth. Comparable terms are epoch, age, period, saeculum, aeon (Greek ''aion'') and Sanskrit yuga. Etymology The word has been in use in English since 1615, and is derived from Late Latin ''aera'' "an era or epoch from which time is reckoned," probably identical to Latin ''æra'' "counters used for calculation," plural of ''æs'' "brass, money". The Latin word use in chronology seems to have begun in 5th century Visigothic Spain, where it appears in the ''History'' of Isidore of Seville, and in later texts. The Spanish era is calculated from 38 BC, Before Christ, perhaps because of a tax (cfr. indiction) levied in that year, or due to a miscalculation of the Battle of Actium, which occurred in 31 BC. Like epoch, "era" in English originally meant " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
