Thanks for the info on this chip: before I bid on it (paid $2) I checked the CC>CC documents to see if it was one of the fakes--it was not shown there. I also noted how worn it was and thus assumed it was not created falsely. I didn't have TCR at the office and so didn't know it was not there. But when I got the chip and then checked and couldn't find it sent the previous post. I still wonder about it since it is so very "used."
