	Smart Computing Encyclopedia Entry - enhanced graphics adapter (EGA)
		EGA is a graphic standard introduced by IBM in 1984 as a contemporary to the IBM PC AT personal computer.
		The EGA standard is not missed; users from the 1980s remember the monitors as fundamentally blurry, so much so that many businesses used monochrome or single-color monitors for years to help their workers see the text on-screen.
		Computers with EGA technology are not usable for much of anything anymore, although they might make nice collectables.

	Enhanced Graphics Adapter (Site not responding. Last check: 2007-11-02)
		The Enhanced Graphics Adapter (EGA) is the computer display standard specification located between CGA and VGA in terms of graphics performance (viz., colour and space resolution).
		EGA can drive an MDA monitor by a special setting of switches on the board; only 640×350 high-res is available in this mode.
		The base IBM EGA card came with 64 kilobytes of video memory installed, actually just enough to handle monochrome high-resolution graphics (but allowing for full colour in the 640×200 and 320×200 modes).

	Enhanced Graphics Adapter : EGA
		Enhanced Graphics Adapter is a graphic display specification between CGA and VGA.
		Introduced in 1984, EGA produced a display of 16 colors at a resolution of 640x350 pixels.
		Each of the 16 colours could be assigned a unique RGB colour via a palette mechanism.

		The Enhanced Graphics Adapter was next in the line.
		It was a nice graphics card at the time, but it couldn't deliver the vast array of colors we all like today, so it is thus forgotten.
		One new feature on the EGA adapter was the memory expansion board.

	IBM PC-Compatible CGA Video Reference
		An upgrade using the IBM Computer Graphics Adapter (CGA) allowed the use of 16 fixed colors for text and four colors (white, fl, purple and cyan) for 320x200 color graphics.
		In 1984, following improvements in graphics resolution and color depth made by other vendors, IBM introduced the Enhanced Graphics Adapter (EGA), which provided all the capabilities of CGA, but allowed more colors while displaying graphics, and a higher number of pixels (dots) for the graphical displays.
		EGA continued to use the same connector that was used for CGA, but the signals that are sent to the monitor are different and not compatible with CGA-only monitors.

		In 1981, IBM introduced the Color Graphics Adapter (CGA), which was capable of rendering four colors, and had a maximum resolution of 320 pixels horizontally by 200 pixels vertically.
		EGA allowed up to 16 different colors and increased the resolution to 640x350 pixels, improving the appearance of the display and making it easier to read text.

	IBM PC-Compatible EGA Video Reference
		In 1984, IBM introduced the Enhanced Graphics Adapter (EGA) for the IBM Personal Computer, which was designed to recover some of the market share lost to Hercules and other manufacturers of video cards.
		The EGA adapter allowed resolutions up to 640x350, and up to 64 fixed colors using a TTL monitor interface, which allowed four different intensity levels from each video gun (Red, Green and Blue).
		EGA was never an enormous success, partly because it required a special EGA-capable monitor and some of the EGA video modes were difficult to write software for.

	Hewlett-Packard Journal: The HP Ultra VGA graphics board - Technical
		The graphics capabilities of the CGA allowed it to display 320 by 200 pixels in four colors, or 640 by 200 pixels in two colors.
		The EGA was fully backward compatible with the CGA (and with the monochrome monitor, the MDA).
		Newer display adapters, such as the HP Ultra VGA board, have taken the next step by increasing the VGA resolution to 1024 by 768 pixels with 256 colors available at all resolutions (increasing the display memory to 1M bytes) and providing some local graphics processing in the video display system.

		The VGA port supports graphics and text modes (including 640 x 480 graphics, 320 x 200 graphics in 256 colors, and 720 x 400 text), and yet maintains compatibility with Color Graphics Adapter (CGA) and Enhanced Graphics Adapter (EGA) modes.
		The adapter transmits and receives at a speed of 4 million bits per second using protocols conforming to IEEE 802.5 and ECMA 89 standards.
		The adapter diagnostic program is used to verify the correct operation of the adapter.

		The Monochrome Display Adapter (MDA, also MDA card) introduced in 1981 was IBM's standard video display card and computer display standard for the PC.
		The MDA did not have any graphics mode of any kind; it only featured a single monochrome text mode (PC video mode 7), which could display 80 columns by 25 lines of high resolution text characters.
		For PC users requiring bitmapped graphics and/or color, IBM offered its Color Graphics Adapter (CGA, also CGA card), launched at the same time as their MDA.

		The EGA card came standard with only 64 KB of memory.
		Then, with the addition of a special IBM memory module kit, you could add another 128 KB, for a total of 256 KB of graphics memory.

		Some monitors that were produced in the late 80s actually have a toggle switch to allow the selection of either digital or analog inputs.
		By modern standards 8514/A is still rather primitive: it supports 1024x768 graphics in 256 colors but only at 43.5 Hz (interlaced), or 640x480 at 60 Hz (non-interlaced).
		XGA-2: This graphics mode improves on XGA by extending 1,024x768 support to high color, and also supporting higher refresh rates than XGA or 8514/A. The closest thing to a true SVGA standard is the set of standards created by VESA.
