The page says they have successfully tested the programmer with the AT89S52 and ATMEGA16L. So if you follow everything as explained in the tutorial, it should work. The ISP uses 74LS08 IC instead of using resistors, capacitors and transistors that other serial programmers use.

So if you are building the ikalogic ISP, you do not need any additional resistors and capacitors. Though you will need the capacitors for the crystal oscillator.

And please do not PM any doubts you have. You may post them in the forum, I will definitely answer them on the forum. When you post it on the forum, you will get replies from a lot of other users and it will also help others with a similar problems.
