Kolorowa przeszłość CGA: pierwsza karta kolorów dla komputerów PC

In the early days of computer technology, the Color Graphics Adaptor (CGA) marked a significant milestone in the history of visual display capabilities for PCs. Although often criticized for its limited color palette and low resolution, CGA paved the way for the vibrant and detailed graphics we enjoy today on modern machines.

During the 1980s, when technology was in its infancy, computer graphics on PCs left much to be desired. The CGA graphics card was mockingly referred to as the “crap graphics adapter” due to its underwhelming performance. Originally designed for displaying bar charts, it was not intended to support the sophisticated visuals demanded by video games. However, this seemingly rudimentary technology inadvertently laid the foundation for the future of computer gaming.

Subsequent advancements in graphic cards, such as the EGA and VGA, greatly enhanced the quality of graphics on PCs, leaving CGA mainly in budget-friendly machines like the Amstrad PC1512. Surprisingly, software compatibility with CGA persisted well into the early 1990s, with even the Windows 3.0 operating system capable of running on this vintage card.

The basic version of CGA utilized a mere 16 KB of memory and supported a palette of 16 colors. In those primitive times, eight of these colors were essentially two intensities of the primary colors – red, green, blue, and black. Additionally, with the inclusion of a fourth bit, users could modify the “intensity” of colors, allowing for a semblance of 4-bit color depth.

Of course, not all 16 colors could be simultaneously displayed on the screen. The text mode offered a 16-color display at a resolution of 640 x 200 pixels, utilizing ASCII code to render shapes and images. While this unconventional approach to graphics required “typing” images rather than drawing them, it provided many with hours of entertainment and creative expression.

In summary, despite its limitations, the CGA graphics card pioneered the realm of color graphics for PCs. Without its groundbreaking contributions, the immersive visual experiences we cherish today might have remained merely a distant dream.
