 		 #99285 - yes, there are many differents!
Responding to: ???'s previous message
Yes, there are many differents between the two circuits, but I use exact the same circuit as the one at 21icbbs(74LS244 or HC244)
it can read and eras the chip under aec_isp, but can not program AT89S52, the circuit only can read the chip under atmel_isp,
I have done it, you can try it!
