Computer Fundamentals

The computer is termed computation. For calculating or computing something the device that has been used is known as the computer. Or we can say that for performing a fast arithmetic operation the device that has been used is a computer. Storing, processing, and retrieving are the main features of a computer. 

Question

How many bits is the OPCODE and what is the assembly language mneumonic for each of the following Pep/9 instruction specifiers (which are given in hexadecimal)?

(use numbers only for the bits and UPPERCASE letters for the mneumonics - do not include the addressing mode for example ADDA and not ADDA 0xFFFF,d)
