I apologize for the duplicate thread...I posted this question under the general Mac forum but no one has responded. I'm hoping someone here will have an idea. I recently sold a Mac IIsi online. Prior to shipping it, I had the computer running effortlessly and tested the majority of the applications. When the buyer received it, he left negative feedback saying that the Mac was out of service and he later reported that 2 of the integrated circuits were unsoldered. He never replied when I asked if the machine turned on. My question is, is it possible to have the computer up & running with these circuits being unsoldered? Is it possible that they may have disconnected in transit? I'm highly suspicious of his claim because he did not request to return the item, but I wanted to double check before I respond to his feedback. Thanks for your help!
