Yes, you can interface a stepper motor using the 8086 microprocessor. This typically involves using output ports to send control signals to a motor driver circuit, which then drives the stepper motor. You would need to write a program to generate the appropriate sequences of pulses to control the motor's direction and speed. Additionally, external components like transistors or H-bridges may be required to handle the motor's current.

Maybe you mean the prefetch queue?
To interface a stepper motor with the 8086 microprocessor using the 8255 Programmable Peripheral Interface (PPI), you first configure the 8255 in mode 0 for simple I/O operations. The control lines of the stepper motor are connected to the output ports of the 8255. The microprocessor sends a sequence of pulses to these ports to energize the motor coils in the correct order, effectively rotating the motor in steps. To achieve a 90-degree rotation, the number of pulses sent corresponds to the required steps based on the step angle of the motor (e.g., for a 1.8-degree stepper, you would send 50 pulses).

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.
Separate bank read strobes are not needed when interfacing memory to the 8086 because the 8086 uses multiplexed address and data lines. This means that the address lines are shared with the data lines, and the control signals generated by the 8086, such as ALE (Address Latch Enable), effectively manage the timing for memory accesses. The 8086 generates the necessary control signals to enable memory reads and writes, allowing it to access memory without the need for additional strobes for separate banks. Thus, the built-in control signals suffice for coordinating memory operations.
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.
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.

One many find this answer on YouTube. One also may find out how to write ascending order programs using an 8086 microprocessor by looking at the owners manual.
The ALE (Address Latch Enable) signal in the 8086 microprocessor is used to demarcate the time when the address bus is valid. It indicates that the multiplexed address/data bus (AD0-AD15) is carrying a valid address during the first part of a bus cycle. When ALE is asserted, external latches can capture and hold the address, allowing the data bus to later carry data without confusion. This functionality is crucial for enabling the proper interfacing of the 8086 with memory and peripheral devices.
