I want the circuit diagram of the ISP cable that works with Atmels "Microcontroller ISP Software".
you can find hundereds on the web by googling and whichever you use, it will not work.
All you find will be 'tested' and I am sure that if you use the originators PC, the originators board and the originators cable it MAY work.
Bite the bullet and spend the $25 to buy the Atmel cable.
This issue is beaten to death five times over here www.8052.com/.../read.phtml
