Hi all friends,
I followed your advices and rearrange the program and check with the hardware. I found that crystal works
at 4 MHz frequency with 1 V pk _ pk magnitude.
I could got signals at PSEN and ALE very clearly. Always port 3 pins are
at low state. After giving a signal to reset terminal(9) port 3 pins are in high state.It seems that address ports ( port 0 and port 2)are working properly.

I have adjusted the time as far as possible.( FF * FF * 5F)
Program was also changed as your advice.
org 0100H

Still I couldn't get the output results. Thank you very much for your kind attentions for my work.
