* Address decoding: PALs were often used to decode memory addresses, allowing for memory bank switching, a common technique in 8-bit computers to expand beyond their native address space.
* I/O interface logic: They simplified the interface between the CPU and various peripherals.
* Example: The Commodore 64 CPC 6128 used a PAL for part of its memory management and bank switching logic.
