However, IBM sold the companion CRT monitor (for use with the 8514/A) which carries the same designation, 8514. The 8514 uses a standardised API called the "Adapter Interface" or AI. This interface is also used by XGA , IBM Image Adapter/A , and clones of the 8514/A and XGA such as the ATI Technologies Mach series and IIT AGX .
The Enhanced Graphics Adapter (EGA) is an IBM PC graphics adapter [2] [3] and de facto computer display standard from 1984 that superseded the CGA standard introduced with the original IBM PC, and was itself superseded by the VGA standard in 1987.
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.
VGA section on the motherboard in IBM PS/55. The color palette random access memory (RAM) and its corresponding digital-to-analog converter (DAC) were integrated into one chip (the RAMDAC) and the cathode-ray tube controller was integrated into a main VGA chip, which eliminated several other chips in previous graphics adapters, so VGA only additionally required external video RAM and timing ...
TGA graphics are built into the motherboards of Tandy computers. The PCjr uses a custom monitor with a unique 18-pin plug, [15] but an adapter (with the same DE-9 connector and pinout as IBM's CGA/EGA) can connect it to the IBM Color Display or similar 4-bit digital RGBI monitor. [16] The Tandy 1000 provides the DE-9 connector directly. [17]
[citation needed] The IBM Enhanced Graphics Adapter (EGA) contained an 8×14 pixels-per-character version, and the VGA contained a 9×16 version. [citation needed] All these display adapters have text modes in which each character cell contains an 8-bit character code point (see details), giving 256 possible values for graphic characters. All ...
The Hercules Graphics Card was released to fill a gap in the IBM video product lineup. When the IBM Personal Computer was launched in 1981, it had two graphics cards available: the Color Graphics Adapter (CGA) and the Monochrome Display And Printer Adapter (MDA).
The CGA and MDA support in the BIOS proper was maintained through the IBM PC XT and PC AT product lines (which did support option ROMs), so that those cards worked (with full BIOS support) in those machines. The first PC video adapter card that had an option ROM was the IBM EGA, introduced in 1984 with the IBM PC AT.
