1. The Basics of Early PC Graphics
1.1. Character-Based Displays
- Text-Only Output: The earliest personal computers, such as the Altair 8800 (1975), lacked graphical interfaces and relied on text-based output.
- Monochrome Displays: Systems like the TRS-80 and Apple I featured black-and-white or green-on-black text screens.
- Resolution: Early text displays had limited resolutions, typically 40×24 or 80×25 characters.
1.2. ASCII Art
- Programmers used ASCII characters creatively to simulate graphics, giving birth to rudimentary visual effects and art.
2. Monochrome and Color Graphics Cards
2.1. MDA (Monochrome Display Adapter, 1981)
The IBM MDA was the first display standard for IBM PCs, designed for business users.
- Resolution: 720×350 pixels (text only).
- Colors: Monochrome (white on black).
- Capabilities: Ideal for text-based applications like word processing and spreadsheets.
2.2. CGA (Color Graphics Adapter, 1981)
IBM’s CGA introduced color graphics to the PC, targeting gaming and home users.
- Resolution and Colors:
- 320×200 pixels (4 colors from a palette of 16).
- 640×200 pixels (monochrome).
- Applications:
- Early PC games like King’s Quest I utilized CGA’s limited color palette.
- Graphics were blocky and limited by color clash, but CGA was revolutionary for its time.
2.3. EGA (Enhanced Graphics Adapter, 1984)
IBM’s EGA improved on CGA, introducing a wider color palette and better resolution.
- Resolution and Colors:
- 640×350 pixels (16 colors from a palette of 64).
- Impact:
- Supported more detailed images and clearer text.
- Games like The Secret of Monkey Island looked significantly better with EGA’s enhanced capabilities.
3. Advances in Graphics Hardware
3.1. VGA (Video Graphics Array, 1987)
The VGA standard, introduced by IBM, set a new benchmark for PC graphics.
- Resolution and Colors:
- 640×480 pixels (16 colors).
- 320×200 pixels (256 colors).
- Applications:
- Widely used in gaming, business software, and graphical user interfaces.
- Titles like DOOM and SimCity utilized VGA for richer visuals.
- Legacy:
- VGA became the standard for PCs throughout the late 1980s and early 1990s, with continued compatibility in modern systems.
3.2. SVGA (Super VGA, 1989)
SVGA expanded VGA capabilities, supporting higher resolutions and more colors.
- Resolution and Colors:
- Resolutions up to 800×600 and beyond.
- Support for 16.8 million colors (24-bit true color).
- Applications:
- Used in advanced gaming, image editing, and CAD software.
- Games like Myst leveraged SVGA for stunning pre-rendered graphics.
3.3. Proprietary Graphics Chips
Some systems developed unique graphics capabilities that set them apart:
- Amiga Computers (1985):
- Used custom chips (e.g., Agnus, Denise) to support 4096 colors and advanced hardware-accelerated graphics.
- Perfect for gaming, animation, and video production.
- Atari ST (1985):
- Offered 16 colors and built-in MIDI support, making it popular for music production and gaming.
4. Gaming and Creative Applications
4.1. Early PC Gaming
Graphics capabilities played a significant role in the evolution of PC gaming:
- CGA Era (1981–1984): Blocky graphics but groundbreaking gameplay.
- EGA Era (1984–1987): More detailed and colorful games, with better immersion.
- VGA Era (1987–1990s): PC gaming came of age with games like DOOM and The Elder Scrolls: Arena.
4.2. Creative Software
Graphical improvements expanded the possibilities for creative applications:
- Deluxe Paint (1985): Revolutionized 2D art and animation, particularly on the Amiga.
- CorelDRAW (1989): Introduced vector graphics to early PCs, paving the way for professional design.
5. Modern Legacy of Vintage Graphics
5.1. Emulation and Retro Gaming
- Tools like DOSBox and RetroArch allow modern users to experience vintage graphics on today’s systems.
5.2. Inspiration for Modern Indie Games
- Retro-style graphics in games like Celeste and Undertale draw inspiration from EGA and VGA aesthetics.
6. Conclusion
