[SOLVED] Simulated result not showing on board AT89s52 using Reads51

hi, im trying to make a simple AT89S52 based POV, and it seems to work in the simulation under reads51 software. however after i made the board and programmed the chip it doesn't do anything all LEDs remain off.

i know the board is working fine because i programmed the chip to flash the LEDs and it seems to be working, but when i program the chip with the POV program it just does nothing. it works in the reads51 ide but not on the real thing? o.0

i think reads51 maybe compiling the hex wrong, im not sure..... can anyone suggest a 8051 assembly compiler thats free?

here is the code for all that like to have a try and see if thier compiler works.
