If you can take a few minutes and see if you have any of the chips on this list, that would be AMAZING!! If you do not know the TCR numbers mesmerized, use the "chip search" function on the Home Page of The Chip Guide and type in the TCR number into the catalog# box. It will bring up the 411 on the chip in question. Thank you for your help!
