ViewMAX
ViewMAX is a CUA-compliant file manager supplied with DR DOS versions 5.0 and 6.0. It is based on a cut-down runtime version of Digital Research's GEM/3 graphical user interface modified to run only a single statically built application, the ViewMAX desktop. Support for some unneeded functions has been removed whilst some new functions were added at the same time. Nevertheless, the systems remained close enough for ViewMAX to recognize GEM desktop accessories ( executables) automatically and to allow some native GEM applications ( executables) to be run inside the ViewMAX environment (without having to install and launch GEM first). Many display drivers for GEM 3.xx could be used by ViewMAX as well, enabling ViewMAX to be used with non-standard display adapters and higher resolutions than possible using the default set of ViewMAX drivers. Also, Digital Research's SID86, the symbolic instruction debugger that shipped with DR DOS 3.xx and provided dedicated functions ...

DR-DOS
DR-DOS (written as DR DOS, without a hyphen, in versions up to and including 6.0) is a disk operating system for IBM PC compatibles. Upon its introduction in 1988, it was the first DOS attempting to be compatible with IBM PC DOS and MS-DOS (which were the same product sold under different names). DR-DOS was developed by Gary A. Kildall's Digital Research and derived from Concurrent PC DOS 6.0, which was an advanced successor of CP/M-86. As ownership changed, various later versions were produced with names including Novell DOS and Caldera OpenDOS. History Origins in CP/M 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. Although CP/M had dominated the market since the mid-1970s, and was shipped with the vast majority of non-proprietary-architecture personal computers, the IBM PC in 1981 brought the beginning of what was eventu ...

GEM/3
GEM (for Graphics Environment Manager) is an operating environment released by Digital Research (DRI) in 1985 for use with the DOS operating system on Intel 8088 and Motorola 68000 microprocessors. GEM is known primarily as the graphical user interface (GUI) for the Atari ST series of computers, and was also supplied with a series of IBM PC-compatible computers from Amstrad. It was also available for the standard IBM PC, at a time when the 6 MHz IBM PC AT (and the very concept of a GUI) was brand new. It was the core for a small number of DOS programs, the most notable being Ventura Publisher. It was ported to a number of other computers that previously lacked graphical interfaces, but never gained popularity on those platforms. DRI also produced X/GEM for their FlexOS real-time operating system with adaptations for OS/2 Presentation Manager and the X Window System under preparation as well. History GSX In late 1984, GEM started life at DRI as an outgrowth of a more gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DOS/V
DOS/V is a Japanese computing initiative starting in 1990 to allow DOS on IBM PC compatibles with VGA cards to handle double-byte (DBCS) Japanese text via software alone. It was initially developed from PC DOS by IBM for its PS/55 machines (a localized version of the PS/2), but IBM gave the driver source code to Microsoft, who then licensed a DOS/V-compatible version of MS-DOS to other companies. Kanji fonts and other locale information are stored on the hard disk rather than on special chips as in the preceding AX architecture. As with AX, its great value for the Japanese computing industry is in allowing compatibility with foreign software. This had not been possible under NEC's proprietary PC-98 system, which was the market leader before DOS/V emerged. DOS/V stands for "Disk Operating System/VGA" (not "version 5"; DOS/V came out at approximately the same time as DOS 5). In Japan, IBM compatible PCs became popular along with DOS/V, so they are often referred to as "DOS/V mac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Runtime System
In computer programming, a runtime system or runtime environment is a sub-system that exists both in the computer where a program is created, as well as in the computers where the program is intended to be run. The name comes from the compile time and runtime division from compiled languages, which similarly distinguishes the computer processes involved in the creation of a program (compilation) and its execution in the target machine (the run time). Most programming languages have some form of runtime system that provides an environment in which programs run. This environment may address a number of issues including the management of application memory, how the program accesses variables, mechanisms for passing parameters between procedures, interfacing with the operating system, and otherwise. The compiler makes assumptions depending on the specific runtime system to generate correct code. Typically the runtime system will have some responsibility for setting up and managin ...

Caldera Thin Clients
Lineo was a thin client and embedded systems company spun out of Caldera Thin Clients by 20 July 1999. History Caldera Thin Clients, Inc., had been created as a subsidiary of Caldera, Inc., on 2 September 1998. Caldera Thin Clients' original President and CEO was Roger Alan Gross, who resigned in January 1999. In April 1999, Caldera Thin Clients released the no longer needed sources to Graphics Environment Manager, GEM and ViewMAX under the GNU General Public License (GPL). In July 1999, Caldera Thin Clients decided on a major refocus on Linux and consequently changed its name to Lineo. Lineo licensed a stripped down OpenLinux distribution from Caldera Systems, Inc., Caldera Systems and named it Embedix. They continued to maintain the former Caldera Thin Clients sales office in Taipei in 1999. In January 2000, Lineo reincorporated in Delaware. Lineo's technologies fully owned were well ahead of competitors' products in the embedded system portion. These technologies include ...

FreeGEM
FreeGEM released in 1999 is a windowing system based on Digital Research's GEM which was first released in 1985. GEM stands for "Graphics Environment Manager". Overview FreeGEM is the free software/open source version of GEM developed after Caldera Thin Clients released the GEM code under the terms of the GNU GPL-2.0-only free software license in April 1999. Caldera Thin Clients owned the source code to GEM through Caldera's purchase of the remaining Digital Research assets from Novell on 23 July 1996, who had acquired Digital Research in June 1991. FreeGEM code works on almost every version of DOS, and runs on almost every IBM compatible PC. One can download all the FreeGEM binaries and source code in one package through the OpenGEM SDK. The OpenGEM SDK also contains language bindings, documentation, and compilers. There are additional FreeGEM resources available through John C. Elliott's GEM website. OpenGEM is a popular FreeGEM distribution. Other distributions include Owe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DOSSHELL
DOS Shell is a file manager that debuted in MS-DOS and PC DOS version 4.0, released in June 1988. It was discontinued in MS-DOS version 6.22, but remained part of the Supplemental Disk. The Supplemental Disk could be ordered or could be downloaded through Microsoft's FTP server. DOS Shell was retained in PC DOS until PC DOS 2000. Overview DOS Shell was one of the first successful attempts to create a basic graphical user interface (GUI) type file manager in DOS, although it is properly referred to as a text user interface (TUI) or Character-Oriented Windows (COW) even though graphical modes were available on supported hardware (VGA-equipped PCs). The shell is very much like a DOS version of File Manager found in Windows up to versions 3.11 and NT 3.51, and File Explorer on later versions. An early incarnation of DOS Shell, titled MS-DOS Manager, was bundled exclusively with the Eazy PC, an IBM PC clone manufactured by Zenith Data Systems in 1987. In MS-DOS ...

GEM Character Set
The GEM character set is the character set of Digital Research's graphical user interface GEM on Intel platforms. It is based on code page 437, the original character set of the IBM PC, and like that set includes ASCII codes 32–126, extended codes for accented letters (diacritics), and other symbols. It differs from code page 437 in using other dingbats at code points 0–31, in exchanging the box-drawing characters 176–223 for international characters and other symbols, and exchanging code point 236 with the symbol for line integral. However, GEM is more similar to code page 865 because the codepoints of Ø and ø match the codepoints in that codepage. The Motorola-based GEM adaptation for the Atari ST family of computers utilized the similar Atari ST character set. It has swapped ¢ and ø and has also swapped ¥ and Ø (to match code page 437 more). It also has the ß (sharp s) at code point 158, reversed not sign (⌐) at code point 169 (as in code page 437), not sign (¬) a ...

File Manager
A file manager or file browser is a computer program that provides a user interface to manage files and folders. The most common operations performed on files or groups of files include creating, opening (e.g. viewing, playing, editing or printing), renaming, copying, moving, deleting and searching for files, as well as modifying file attributes, properties and file permissions. Folders and files may be displayed in a hierarchical tree based on their directory structure. Features File transfer Graphical file managers may support copying and moving of files through " copy and paste" and "cut and paste" respectively, as well as through drag and drop, and a separate menu for selecting the target path. While transferring files, a file manager may show the source and destination directories, transfer progress in percentage and/or size, progress bar, name of the file currently being transferred, remaining and/or total number of files, numerical transfer rate, and graph ...
