Generic PC with Monochrome Display Adapter (MDA) (c) 1981 None

The MDA is IBM's standard video display card and computer display standard for the PC introduced in 1981.

- TECHNICAL -

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.

- TRIVIA -

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.
