8FD

8FD is a hexadecimal value that represents a specific byte in computing. In the context of the 6502 microprocessor, which was widely used in early personal computers and video game consoles, 8FD is a memory address.

The 6502 microprocessor uses a 16-bit address bus, allowing it to access up to 65,536 (2^16) different memory locations. The address 8FD is a specific location within this address space. It is often used in the context of assembly language programming for the 6502, where programmers might refer to specific memory addresses to store data or execute instructions.

In the hexadecimal system, 8FD is composed of two nybbles: 8 and FD. The nybble 8 represents the higher-order bits, while FD represents the lower-order bits. This address can be converted to its decimal equivalent for use in calculations or other contexts.

8FD is also significant in the context of the Commodore 64, a popular home computer of the 1980s. The Commodore 64 uses the 6502 microprocessor and has a specific memory map, where certain addresses are reserved for particular functions. The address 8FD might be used in this context for accessing or manipulating specific hardware components or memory-mapped I/O.

Understanding the address 8FD requires knowledge of the specific system and its memory map, as different systems can have different uses for the same address. In summary, 8FD is a hexadecimal value representing a specific memory address in the 6502 microprocessor's address space, with potential significance in systems like the Commodore 64.
