Some Progress Today:
The 2 motherboards had their warm Alconox bath today. I mixed a warm bath in a 5 gallon bucket and then dunked and lightly brushed both boards with a plastic bristle large glassware brush. All of the capacitor goo was cleared and the boards immediately began to sparkle. Even the offending aluminum electrolytic CAPs were rendered shiny. I rinsed under a deionized water tap and then double rinsed them again immersed in deionized water. I then dried the boards using nitrogen. (yes, I work in a Lab)
The 2 boards came out looking great. I am more partial to how the newer board (from the crappier sunburnt SE/30 case) looks. It has a highly glossy smooth finish that is comparable to that form my Iici, if it had metal clips for the SIMMs it would be absolutely perfect. That warm yellow region in the lower right center is just an artifact of the light or the camera's flash. The other older board from the nice looking case has more of a satin finish to it and seems a bit more irregular. The backsides of both boards looked fine.
Here is a relatively high resolution side by side of my results go ahead and click on it for the zoom-in.

I sent a PM to trag like I did almost 4 years ago on my Iici to score some Ta replacements. One thing that looks promising is that unlike on my Iici, the old CAPs here may not be glued in addition to the solder. That would definitely make the upcoming job easier. I plan to buy my own hot tweezer iron for this job instead of borrowing one last time.
I can't wait to see what will happen when I go to do the boot up. I will even take the checkerboard or stripes. With the great knowledge base here I am confident these boards will be tackled. I plan on playing a nice game of columns or the original Mac Solitaire from 1984.
In the meantime I plan to do some iMacG4 rehab (also CAPs) while I wait for the new Ta CAPs...
