Write a 8085 assembly language program which will be interrupted by giving a rising signal at RST 7.5 input. The program will copy 512 bytes of data which is stored at memory location starting from 1235H to memory location starting from 9999H. The interrupt signal should, however, be able to introduce a delay of 1 sec. Once the delay finishes, it should then move to the main program. The main program for moving the data is in a loop that reruns the same task repeatedly.

Using the MARIE computer assembly language, write a program that computes the following expression:z = a * b * c. The computer will read in the input values a, b, and c from the keyboard and the final result(z) have to be displayed. In addition, every time an input value is read in, it must be displayed on the screen.Remember that the instruction set does not have an instruction to execute multiplication.Note: If any of the input values a, b, and c is a negative numbers or a zero, then the result printedshould be “0”. Otherwise, the result of the multiplication must be printed. The program must be tested on MARIE simulator.
