So these chip are erasable? Best news for me today!

and you asked me if i was living in Laval... well i live 15 min away from laval... Ste-Thérese/Rosemere when i go to school, but i live in Mont-Tremblant for the summer

 

Yes, they are actualy Re-writable. No need to erase, just burn over them. Cheapass's like myself go for the 27c's that you need to erase

 

Yeah, with your Willems just hit the Burn button. It will write over the old .bin
