i have been having a shitload of trouble burning these chips with the willem burner, even following step-by-step the numerous walkthroughs of setting the jumper and taking it out and setting the offset to 8000 and all that.
here is my question:
i know these chips require 12.75v to burn them. but using usb for power on the burner, i shouldnt be able to get any more than 5v i would think... do i need the a/c wall adapter to be able to provide the 12.75v to burn these chips? if so where could i get one of those?

 

Radio shack etc.I used my power cord for a cell phone charger.

 

---- sst's too complicated to erase. status bar keeps reading that it erased but when i go to burn a chip on over it says error after its done burning i'll buy amtels :1

 

Are you guys removing the jumper to burn and putting it back to erase? Thank usually does it.......and make sure the half moon shape is facing towards the lock lever on the burner.

 

It took me a while to figure that one out when i first got mine but after that it was cake.

 

doing all that, using jumpers, everything. still getting nothing.

 

why not write what you did and we will try to see if we catch anything...usb and parallel printer port right?
