Can someone tell me what chip this is? http://vintagecomputer.net/pictures/2017/Objects/P1010114.JPG http://vintagecomputer.net/pictures/2017/Objects/P1010093.JPG http://vintagecomputer.net/pictures/2017/Objects/P1010094.JPG
(note ..94/94 show the item in a sealed in storage material) the underside consists of 4 sets of 12 pins plus the corner 3 pins, as shown on the top of the chip. thanks
