I got this motherboard from a really beat up N64 I grabbed on ebay. It was listed as "tested and working" but alas, it will only power on and refuse to recognize a cart or display anything on screen. I've relocated the cart slot, as it seemed loose, to troubleshoot the problem but with no success. Nothing else has been desoldered and board comes as is with no Jumper Pak or hookups. I'd be happy with ~$10 or some equal trade.
