What is the Color RAM Address of the C64?
The Commodore 64 (C64) is a legendary 8-bit home computer that was released in the 1980s. It was known for its impressive graphics and sound capabilities, which were made possible by its unique color RAM address. In this article, we will explore the color RAM address of the C64 and what it means for the computer’s performance.
Direct Answer: What is the Color RAM Address of the C64?
The color RAM address of the C64 is 55296 ($D800). This address is used to store the color palette for the computer’s graphics, and it is an essential part of the C64’s graphics capabilities.
Understanding the Color RAM Address
The color RAM address is a 16-bit address that is used to access the color palette of the C64. The address is divided into two parts: the high byte and the low byte. The high byte (bits 15-8) specifies the color index, while the low byte (bits 7-0) specifies the color value.
Color RAM Address Range
The color RAM address range is from 55296 ($D800) to 56295 ($DBE7). This range is used to store the color palette for the computer’s graphics, and it is an essential part of the C64’s graphics capabilities.
How to Use the Color RAM Address
To use the color RAM address, you need to set the color index and color value using the following formula:
*Color Value = (High Byte 16) + Low Byte**
For example, if you want to set the color index to 5 and the color value to 12, you would use the following formula:
*Color Value = (5 16) + 12 = 80**
You would then store this value in the color RAM address 55296 ($D800).
Color RAM Address in Action
The color RAM address is used in various C64 games and demos to create colorful graphics and animations. For example, the game "Defender of the Crown" uses the color RAM address to create a colorful and animated battle scene.
Conclusion
In conclusion, the color RAM address of the C64 is 55296 ($D800). This address is used to store the color palette for the computer’s graphics, and it is an essential part of the C64’s graphics capabilities. By understanding how to use the color RAM address, you can create colorful and animated graphics and animations for your C64 games and demos.
