The MN/MX- ping on the 8086 is pin 33.
The most significant difference between the Intel 8085 and 8086 microprocessors is that the 8085 is an 8-bit system and the 8086 is a 16-bit system. This difference allows the 8086 system to have a much larger set of operational instructions and can make calculations to more significant places. Note: the 8085 processor does have two 16-bit registers. The pointer and the program counter.

The 80386 was a third generation version of the 8086/8088 microprocessor. The second generation was the 80286, adding protected mode. The 80386 added 32 bit mode, virtual 8086 mode, and flat 32 bit protected mode.The 80386 fixed the problem of the 80286 where existing object code was not compatible in protected mode because the meaning of the segment registers changed. The 80386 allowed the operating system to run in protected mode while presenting the process with a virtual 8086 environment where the segment registers worked as before. This was a stop-gap measure that worked until the full implementation of a true 32 bit flat memory model operating system and software.

Pin 28 on the 8086/8088 is M/IO-, in minimum mode. The equivalent pin on the 8085 is IO/M-, and has opposite polarity.
the question is not clear. the chip with which 8086 has to be interfaced should be mentioned. for example, interfacing 8086 and 8087( NDP) or 8086 and 8255( PPI) or 8086 and 8259( PIC) or 8086 and 8089( IOP) But to make the answer complete I would like to mention 2 references 1.Douglas Hall, "Multiprocessors and Interfacing , Programming and Hardware", Tata Mcgraw-Hill.1999, second edition. 2.John Uffenback, "8086/88 Interfacing, Programming and Design", 1987, PHI.
first connect the 8255 to the 8086 microprocessor and configure it using the CWR then connect the key board to the 8255
8086 has two blocks Bus Interfacing Unit(BIU) and Execution Unit(EU).The BIU performs all bus operations such as instruction fetching, reading and writing operands for memory and calculating the addresses of the memory operands. The instruction bytes are transferred to the instruction queue.EU executes instructions from the instruction system byte queue.Both units operate asynchronously to give the 8086 an overlapping instruction fetch and execution mechanism which is called as Pipelining. This results in efficient use of the system bus and system performance.BIU contains Instruction queue, Segment registers, Instruction pointer, Address adder.EU contains Control circuitry, Instruction decoder, ALU, Pointer and Index register,Flag register.
The 8086/8088 is a 16 bit computer running on a 20 bit address bus. Processes use a segmented memory architecture to access one of four 64kb memory segments from a physical space of 1mb.
The differences are given below: 80286 1. Low data bus width (16 bit) 2. Returning from protected mode to real mode is hard and complicated. 3. Small RAM/Memory 80386 1. High data bus width (32 bit) 2. Easy for 80386 3. Big RAM / Memory (Real memory = 4GB and virtual memory= 64TB)
The 8086 Microprocessor operate to require frequency that is provided by clock generator to 8086 Microprocessor and also Synchronization various component of 8086.
8086 main application is to evaluate the arithmetic operations in any systems that uses 8086
If you mean greater (more) 8086.
