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 ...
Motorola 6845 CRT controller. The Motorola 6845, or MC6845, is a display controller that was widely used in 8-bit computers during the 1980s. [1] [2] Originally intended for designs based on the Motorola 6800 CPU and given a related part number, it was more widely used alongside various other processors, and was most commonly found in machines based on the Zilog Z80 and MOS 6502.
The first version of the MIPI DSI, version 1.0 was released in 2005. MIPI DSI v1.1 was released in 2007, and added features such as "Command Mode" for directly sending commands and data to display modules using the display controller. [1] DSI v1.2 was released in 2011, and extended the video packet length and expanded the command mode. [2]
Common sizes are one row of eight characters (8×1), and 16×2, 20×2 and 20×4 formats. Larger custom sizes are made with 32, 40 and 80 characters and with 1, 2, 4 or 8 lines. The most commonly manufactured larger configuration is 40×4 characters, which requires two individually addressable HD44780 controllers with expansion chips as a single ...

Front page of a floppy disk controller data sheet (1979) A datasheet, data sheet, or spec sheet is a document that summarizes the performance and other characteristics of a product, machine, component (e.g., an electronic component), material, subsystem (e.g., a power supply), or software in sufficient detail that allows a buyer to understand what the product is and a design engineer to ...
A standard-sized 8-pin dual in-line package (DIP) containing a 555 IC.. Integrated circuits and certain other electronic components are put into protective packages to allow easy handling and assembly onto printed circuit boards and to protect the devices from damage.
In 1971, Lechner, F. J. Marlowe, E. O. Nester and J. Tults demonstrated a 2-by-18 matrix display driven by a hybrid circuit using the dynamic scattering mode of LCDs. [3] In 1973, T. Peter Brody , J. A. Asars and G. D. Dixon at Westinghouse Research Laboratories developed a CdSe ( cadmium selenide ) TFT, which they used to demonstrate the first ...
