The Yamaha V9938 is an improved version of the TMS9918, and was mainly used in the MSX2. The Yamaha V9958 is the Video Display Processor (VDP) mainly used in the MSX2+ and MSX turboR computers. The VLSI VS21S010D-L is a 128kB SPI/parallel SRAM with an integrated video display controller with variable-bit-depth pixels and a block-move blitter.
Each screen character is represented by two bytes aligned as a 16-bit word accessible by the CPU in a single operation. The lower (or character) byte is the actual code point for the current character set, and the higher (or attribute) byte is a bit field used to select various video attributes such as color, blinking, character set, and so forth.

The signal standard and pinout are backward-compatible with CGA, allowing EGA monitors to be used on CGA cards and vice versa. Early VGA cards also used this connector. VGA connector (DE-15) Became a nearly ubiquitous analog computer display connector after first being introduced with IBM x86 machines. Older VGA connectors were DE-9 (9-pin).
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 ...
VESA BIOS Extensions (VBE) is a VESA standard, currently at version 3, that defines the interface that can be used by software to access compliant video boards at high resolutions and bit depths. This is opposed to the "traditional" INT 10h BIOS calls, which are limited to resolutions of 640×480 pixels with 16 colour (4-bit) depth or less.
A VGA extender is an electronic device that increases the signal strength from a VGA port, most often from a computer. They are often used in schools, businesses, and homes when multiple monitors are being run off one VGA port, or if the cable between the monitor and the computer will be excessively long (often pictures appear blurry or have ...
Assembled Project VGA graphics board Open Graphics Project prototype. Project VGA aims to create a low-budget, open-source VGA-compatible video card. [104] The Open Graphics Project aims to create an open-hardware GPU. The Open Graphics Device v1 has dual DVI-I outputs and a 100-pin IDC connector.
