If you want to get both working I highly recommend you contact Jean at Amiga Center of France. He will repair both boards in no time flat and have them back to you in perfect working order! His prices are descent too. I paid $100 to get both A600s repaired) I sent him my two dead A600 MBs the beginning of Nov and by Nov 24th I was having fun reassembling and playing games on my A600s!
