This is N4075 in TCR. If you missed the one like this that sold on eBay for $500 or if your offer was declined for the one currently listed with a BIN price of $2,200 you may be interested in this chip. It doesn't come up for sale very often.

I'm offering it here for $400 based on the condition. First to hang a sign or email me takes it.

Payment by Paypal or money order only. Price includes delivery to the U.S.
