Take a look at the second circuit of this site

Thanks ABSF ... But i want to ask somethink.. Do i need use Female to Female Jumper Wire(WR-JW-FF10) to connect at89c52 with avr usbasp...

The website given by Allen is for AT89S instead of AT89C.
USBASP is an ISP programmer but AT89C52 only support parallel programming. Therefore, i don't think USBASP can program the AT89C52.

hyng is right. At first I thought that both the 89c52 and 89s52 are the same. But the follow link shows that they are not :

http://wiki.answers.com/Q/What_is_the_difference_between_AT89S52_and_AT89C52

Page 15 of the datasheet also indicates that all the address lines A0-A12 has to be there during programming the chip.

You still can get the programmer from eBay:

I still have 4 PDIP 89c52, 9 pcs of 89c51 in SMD and 3 tubes of PLCC 87C52 in my stock. I bought my programmer from Canada 3 yrs ago.

You can get universal programmers that can also program at89c51 mcu from element14 or RS components. But they are not cheap. One of them is here:

Or you can build it yourself.

To do the above programmer you need to find a way to program the first 89c51. If you dont have a friend or a shop that can help you to program the first 89c51. You can always contact the author of the project or all the members here to see if anyone can help you. I am sure some of the Labs in Uni still have this programmer.
