Please read this it will give you a lot of info.

           ************************************************
           *             What is this program             *
           ************************************************

The program is an 8085 microprocessor kit emulator, i.e., it emulates a
8085 microprocessor on the host machine it is running.
The emulator uses a virtual machine to recreate the microprocessor on the
the host machine.  The emulator also supports the system calls as
documented in the Intel SDK(Software Development Kit).  The emulator also
includes a assembler, a debugger and an interface. The virtual machine is
written in a high level language (C) and hence is portable, but the
interface is machine dependent.




           ************************************************
           *           How to use the emulator            *
           ************************************************

The program as such contains an assembler a debugger and an interface.
The emulator accepts an 8085 assembly file, parses it, and checks for
syntax errors.  If assembling is through, it loads the assembled binary
image into the virtual machine and passes control to the debugger.
At this stage the user gets control and can either step through the code
or just run it.

 # How do I specify which 8085 assembly file to run.
      There are two ways for this.  In the first method just pass the
      name of the file as a command line parameter to emulator when
      you start the emulator.   i.e., 8085.EXE <8085-assembly-file>.
      The second way is useful when you are already running a program and
      want to load a new program.  For this just press 'Alt+S'(this stops
      the current program) and then press 'F3' to get to the 'new file'
      command. (You must supply the entire file name).

 # What is the format of the 8085 assembly file.
      The 8085 assembly file is a plain ASCII text file containing
      8085 assembly code mnemonics and data.

 # What do I do after loading the program.
      After the program is loaded you are placed in the debugger.
      The debugger and the interface work hand in hand to give you the
      latest update about registers and memory location.
      Simple keys are provided to step through the code, toggle break
      points etc. For more details see the online help on 'hot keys'.
      (F7 -single step, F8 - step over , F9 - Run).

 Note :-  Please always look at the status line about what you can do next.
          Get familiarized with the hot keys, by reading the Help on
          hot keys, it helps you dig out various features of the emulator.


 # What are the various windows that are displayed.

   (first row, left to right)
   1. Code box(mnemonics equivalent of the 8085 binary).
   2. register box
   3. memory dump (memory dump in hex)
   4. flag box (the different 8085 flags)
   (second row, left to right)
   1. Led display (see help for 'system calls' )
   2. Stack box




           **************************************************
           *   Just try these sample 8085 assembly programs *
           **************************************************

 1. scroll.85 and scroll2.85    - Run the program by pressing F9.
    Just watch the LED display scroll in a infinite loop.
    (press 'Alt+S' to stop the machine or press 'F7' to switch
     to single step mode)

 2. bubble.85   - Bubble sort program.  10 data elements are kept at
    position 251(hex).
    Do this - Use tab to switch to the 'memory dump box', press F5
    and key in 251 to goto location 251(hex), now press 'F9' and
    watch the numbers being sorted.

 3. readdisp.85 - Read two keys from the keyboard and display it in the
    rightmost two LED's.
