Defender - Need help locating 5101 and 4071 CMOS Chips on CPU

I'm a noob to fixing arcade machines and I need your help finding the 5101 and 4071 CMOS chips on the CPU board of my Defender. I'm pretty sure the 5101 is the only 22 pin chip on the board (circled on attached pic). Is that correct? Where is 4071 chip in relation to that circled chip?

My Defender is stuck on the set-up screen and from what I've read on this and other forums, the replacement of these two chips is a good place to start.

Thanks for your help!
Jim
