Tektronix TLA 614 CMOS or NVRAM location

[gearheadgeek]

Hello people I will cut straight to the point. I acquired and Tek TLA 614 with a broken screen after determine it can be fixed I got a screen but what I wanted to do is the same thing I did to my TLA 704 is upgrade to a external CMOS battery and a SSD drive and the 704 went off without a hitch no problem but the 614 well I searched the internet for a battery location but could not find one but I did find out about the NVRAM chip. I seen where people replace those but that might be above me. I'm just a old tinker who like to take things apart to see how they work or fix them and give them away. do you think you guys could help me on this it would be much appreciated
             thanks in advance

It's not easy, backup first.

Replacing the NVRAM chip is an option. However, it's not at all easy.
