Generic PC with Monochrome Display Adapter (MDA) © 1981 None
The MDA is IBM's standard video display card and computer display standard for the PC introduced in 1981.
Based on the IBM Datamaster's display system, the standard IBM MDA card uses the Motorola 6845 display controller and is equipped with four kilobytes (kB) of video memory.
The MDA's high character resolution (sharpness) is a feature meant to facilitate business and wordprocessing use: Each character is rendered in a box of 9×14 pixels, of which 7×11 depicts the character itself (the other pixels being used for space between character columns and lines). Some characters, such as the lowercase M, are rendered eight pixels across.
