Hmmm. Well if you intend to sell the 128K, then yes for some collectors, sockets upset the authenticity. The reality is, it should have had sockets, but Jobs nixed it. Any one of us on this board would LOVE to get a sockets 128K or 512K. Or hell, any Mac!

Soldering on a 128/512K circuit board is one of the easiest soldering jobs you'll ever see. Get yourself an old circuit board and a soldering iron and learn the basics. Otherwise, owning vintage Macs will eventually cost you a lot in repairs.
