What do you mean by different operating voltage? Are you talking about Vcc or the output voltage of port pin when it is at logic 1? Well if you see that output voltage at port is low, then use pull-up resistor network of 10k on each port.
I recently bought AT89S52 insted of AT89C52 and it works well for me without any trouble.
