@Charles Kline I may be new to this forum, but how does your nitpicking contribute to the discussion? Someone else is going to search for this and have to read a bunch of obfuscatory comments about how it's been answered before. It happens with search results everywhere. The original answer gets buried beneath a hailstorm of "YoU diDn't reSearch the ProBlem!!" I did and still had more questions specific to my case. Leave it at that.
I'd suggest you use the
advanced search. The regular search is pretty worthless unfortunately (at least the last time I tried it).
There are many articles about R30 going up and taking a part of the board with it, including damaging the pads.
For example:
People who eat right, exercise and maintain a healthy weight still die form heart attacks.... Because heart disease is GENETIC. I should know. I was running 4 to 8 miles a day, and the doctors said "This shouldn't be happening to you." Comparing a disease to corrosion isn't quite comparing...

I am using a missile command harness without a board to test AR output. I tested them with the rig before and no problems at all. I was checking the voltages at the edge connector. I replaced the 3055's on all of them and when I went to test after a few seconds the magic smoke appeared. It did...

I have a working Centipede. Well...I'd say it works 98%. When you shoot any of the Centipede pods, the explosion sound is kinda distorted. Like a little crakeling, muffled or cut off. I know the inside of this machine has been kinda hacked up so I've been putting this off, but now I need to...

Which direction do these Resistors & diodes go? Hi guys, I am rebuilding the Regulator / Audio II board for my Pole Position cockpit. As you can see the R 29 flamed out. I have everything replaced, except the two resistors and two diodes. Diodes CR1 and CR4 Resistors R29 and R30 Which way...

I have a dedicated Centipede that recently stopped working. I'm hoping for some troubleshooting advice, that may narrow down a component(s) to check or replace. Symptoms: The screen is blank, but the monitor has neck glow and when power is turned off, there is a visible collapsing of screen...

It isn't nitpicking the discussion. There is a long argument between those who believe the original "sense circuit" which was intended to "sacrifice" a few cents in cheap resistors (provided they are elevated above the board) instead of cooking and damaging the edge connector of the main board, which is harder to fix (and in the old days, would have likely resulted in the board being scrapped.)
Then you have the "sense mod" gang here, who believe you just replace the resistors with wire, and if the edge connector cooks off, you just fix it. You also should clean the edge connector periodically, since it's "tinned" and tin corrodes resistive (which starts this whole problem in the first place.)
A more expensive solution would have been to silver plate the copper pads for the edge connector or gold plate them so they don't corrode, but Atari didn't do that.
I tend to stick with the "intent" of the original design, so I'd rather see the game fixed by replacing R30 and the other associated components, cleaning the main board edge connector, making sure the edge connector "connections" are good / tight / making good contact, and drive on.
However, it is your game. Do with it what you will, but understand this is a "Preservation" forum, so if you say you are going to mame this and put in a 60 in 1 board, expect to be flamed.
Fair enough? Welcome to the fun!
(You inadvertently stirred up the trolls defending each position, so your thread gets hijacked by those people as they ad-nauseum pose their positions (again)).
