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.

Monochrome Display Adapter: Notes This document describes the behaviour of IBM's original Monochrome Display Adapter and some compatible cards. The MDA is a monochrome card and displays on a TTL monochrome monitor.

Convert MDA, Hercules, CGA, and EGA video signals to VGA for use with a modern monitor. Run your vintage PCs with their native video cards for best old software compatibility. Features: FPGA-powered, providing a lag-free conversion.

The MCA-Adapter is a device, which can convert MDA (and Hercules), EGA and CGA to analogue RGBS signal. It supports following features. Converts digital MDA, Hercules, CGA and EGA to analog RGBS or RGBHV/VGA signal; Color DAC for 3, 4, 16 and 64 color modes; Switchable composite sync from H- and V-Sync; Loop through HV-Sync, colors conversion ...

Vintage new old stock in factory packing PC/XT/AT ISA CGA Color Graphics Adapter and Monochrome MDA (not Hercules, just like IBM monochrome adapter) Card with composite RCA and header video output port. 100% Works. Model ACV-1030. Fully replaces and compatible with IBM CGA and MDA cards.

This device works as a frame buffer to capture an incoming signal, and convert it to a format which can be displayed on a standard VGA monitor. Monochrome MDA signals are converted to 720×400 @ 70Hz, CGA is converted to 720×480 @ 60Hz …

The Monochrome Display Adapter (MDA, also MDA card) introduced in 1981 was IBM's standard video display card and computer display standard for the PC. The MDA did not have any graphics mode of any kind; it only featured a single monochrome text mode (PC video mode 7), which could display 80 columns by 25 lines of high resolution text characters.

Nov 12, 2023 · Short for Monochrome Display Adapter, MDA is the first text-only video display standard from IBM capable of displaying at a maximum of 80x25 characters in two colors. Because of its limited characters, HGA (Hercules Graphics …

Jan 7, 2015 · I have an IBM 5151 monochrome monitor with a DE-9 connector for MDA. I would like to connect this monitor to a newer computer with a DE-15 connector for VGA. Since these are two different display standards, I need an adapter to …

A simple standalone MCA/CGA/EGA to VGA adapter based on a raspberry pi Pico. The Pico reads the TTL input video signal, writes the pixels to a buffer and then generates the VGA signal using the pixels from the buffer. No need for a VGA upscaler or a 15KHz VGA monitor. Works with standard VGA modes. Two PCB variants, one SMD and one Through-Hole.
