The Monochrome Display Adapter (MDA, also MDA card, Monochrome Display and Printer Adapter, MDPA) is IBM's standard video display card and computer display standard for the IBM PC introduced in 1981. The MDA does not have any pixel-addressable graphics modes, only a single monochrome text mode which can display 80 columns by 25 lines of high ...
The term "array" rather than "adapter" in the name denoted that it was not a complete independent expansion device, but a single component that could be integrated into a system. [11] Unlike the graphics adapters that preceded it (MDA, CGA, EGA and many third-party options) there was initially no discrete VGA card released by IBM. The first ...
IBM MDA, CGA and EGA monitors, all supported by the EGA card. The original IBM EGA was an 8-bit PC ISA card with 64 KB of onboard RAM. An optional daughter-board (the Graphics Memory Expansion Card) provided a minimum of 64 KB additional RAM, and up to 192 KB if fully populated with the Graphics Memory Module Kit. [22]
In addition to an MDA-compatible text mode, it offered a monochrome graphics mode with a resolution of 720×348 pixels, higher than the CGA. Also in 1982 the Plantronics Colorplus board was introduced, with twice the memory of a standard CGA board (32k, compared to 16k).
In the realm of IBM PC compatibles, the early standards included Monochrome Display Adapter (MDA), Color Graphics Adapter (CGA), Hercules Graphics Card, Enhanced Graphics Adapter (EGA), and Video Graphics Array (VGA). Each of these standards represented a step forward in the ability of computers to display more colors, higher resolutions, and ...
The 5151 was designed to work with the PC's Monochrome Display Adapter (MDA) text-only graphics card, but the third-party Hercules Graphics Card became a popular companion to the 5151 screen because of the Hercules' comparatively high-resolution bitmapped 720×348 pixel monochrome graphics capability, much used for business presentation ...
The modern DE-15 connector can carry Display Data Channel to allow the monitor to communicate with the graphics card, and optionally vice versa. [1] Being replaced by DVI from 1999 onward. DB13W3: Analog computer video, color and monochrome. Sun Microsystems, Silicon Graphics, IBM RISC, Intergraph and some Apple Computer computer workstations.
Professional Graphics Controller (PGC, often called Professional Graphics Adapter and sometimes Professional Graphics Array) is a graphics card manufactured by IBM for PCs. [1] It consists of three interconnected PCBs , and contains its own processor and memory.
