Write an assembly language program for 8085 microprocessors to read consecutive memory locations from 2000 to 2FFF & transfer to 4000 to 4FFF, if interrupted display the current count at port5 this is for 8085 microprocessor for interrupt we have to write a program & subroutine.

You are given a 2n2222A transistor. It has a B of 255 and an Early Voltage of -74V. (From the datasheet). A) Design a circuit to give you an overall voltage gain magnitude of 200 with an input resistance of at least 5KQ. Your load resistance is 220KO. You have a +12V supply and a -12V supply (you don't have to use both). Your supply of parts

For the circuit of Figure 5, choose values for resistors R1, R2, Rs, R4, Rs, R6, and Rioad (all resistances must be greater than 1 kN). Given that the voltage source Vsi 14 V (show your work for each part) Find the Thevenin equivalent for the circuit between terminals eg. Calculate the theoretical values of a. (1) The Thevenin voltage source
