According to a diagram I saw here A2, B, the 8086' s address lines A0, A3 are connected to an address decoder' s input pins A C. The output pins of the address decoder are connected each to a CS pin of a PIC. 8259ATHE CASCADE BUFFERCOMPARATORThis function block stores compares the IDs ofall 8259A’ s used in the system The datasheet associatedthree IO pins ( CAS0- 2) are outputs when the 8259Ais used as a master are inputs when the 8259Ais used as a slave As a master the 8259A sendsthe ID pic of the interrupting slave device onto theCAS0 – 2 lines The slave thus selected will send itspreprogrammed. 8259A Programmable Interrupt Controller.


Datasheet

The NEC V20 ( μPD70108) was a processor made by NEC that was a reverse- engineered, pin- compatible version of the Intel 8088 with an instruction set compatible with the Intel 80186. The V20 was introduced in 1982, and the V30 debuted in 1983. The chip featured much more than the 29, 000 transistors of the simpler 8088 CPU, ran at 5 to 10 MHz and was around 30% faster ( application dependent) than. Intel Chipset 8259 Datasheet. The 8259A is the Interrupt Controller in the PCs chipset.
