Help please 
Design a computer system with an 8-bit address bus. an 8-bit data bus and it uses isolated I/O. It has: 128 bytes of EPROM starting at address 00H (H meaning in hexadecimal) constructed using 64 times 4 chips, 64 bytes of RAM constructed using. 16 times 8 chips, an input device with a READY signal at address ABH; an output device with a READY signal at address CDH; a bidirectional input/output device with no READY signal at address EFII Please design the computer organization for this system (Choose an appropriate starting address for the RAM by yourself, and use a decoder to enable memory chips). Include all enable and load logic How many 64 times 4 memory chips do we need to construct the EPROM of 128 bytes? Show how you get it? How many 16 times 8 memory chips do we need to construct the RAM of 64 bytes? Show how you get it? Show the address range (i.e., the first address and the last address) for EACH of the EPROM chips? What starting address do you choose for the RAM? Based on your choice of starting address for the RAM in Part (d). show the address range (i.e., the first address and the last address) for EACH of the RAM chips? What is size of the decoder you choose to enable the memory chips? Explain your choice. Show your COMPLETE design for this system.
