Line 18:
One of the best known PICs, the [[Intel 8259|8259A]], was included in the [[x86 architecture|x86]] PC. In modern times, this is not included as a separate chip in an x86 PC, but rather as part of the motherboard's [[Southbridge (computing)|southbridge]] chipset. In other cases, it has been replaced by the newer [[Advanced Programmable Interrupt Controller]]s which support more interrupt outputs and more flexible priority schemas.
