This thread on fake ZIF sockets triggered a memory. Over a year ago (June 2003) I brought a few ZIFs from Futurlec, including these ones . I haven't used them, so I dug them out of the parts box. Sure enough, stamped TFXTODL, part #218-3345, and patent #3500745. Looks like these have been around for quite a while. Note that Futurlec never claim that they are the 3M brand. With hindsight, you notice that in the photo, the arm obscures the writing on socket... As Jan-Erik said, they'll work ok. Here's a page on other fake parts , and more on fake stuff in general . Doesn't mention how the Mafia made fake butter in Italy/Sicily a few years ago. Tony -- http://www.piclist.com#nomail Going offline?
