Question $3$: $[45$ pts$.]$

a$)$ Show the detailed memory map for an $8088$ system with $64$ Kx $8$ RAM using $16$ Kx $8$ RAM chips starting at address $60000$ H $.$

b$)$ Demonstrate how four switches and two seven segment displays $($SSDs$)$ must be connected to a $8088$ system using the $82$C$55$ Programmable Peripheral Interface $($PPI$)$ at addresses COH,$C1H,C2H$ respectively.

c$)$ For part $b,$ write a program to read the binary number formed by the previous four switches and display it as hexadecimal digit on one SSD and display $0$ on the second SSD if it is odd and $E$ if even. For example, if the switches form the odd binay number $1001,$ the SSDs display $09,$ while for the even binay number $1100,$ the SSDs display EC$.$ Assume a lookup table $($Table$)$ that stores the values of SSD for hexadecimal digits.
