Who else has their first computer that was an Apple ][? Where did you get it

I still have the Apple //c I purchased in 1986 from the Upstate Computer Shop in Whitesboro NY. I bought it, an Apple ImageWriter II, and a UniDisk drive for just shy of $1600.00. A few years later I bought and installed an Applied Engineering Z-Ram Ultra III.
I just recently took it out of storage and it appears I have some repair work to do. I can get the machine to boot, but attempting to run anything other than Basic.system, I get a "restart..." message. Upon opening the case, I've seen that the soldered battery backup for the Ultra III RAM board has leaked all over. Time to do some trace cleanup and repair. :)
Any tips on how to make this repair and where I can find a suitable battery replacement would be appreciated. I'd like to get this system working as I have a lot of "Software of the Month Club" diskettes that I'd like to review. :) 

Thanks in advance.

First I'd remove the Ultra III RAM Board to see if every thing functions as expected, unless there is obvious damage to any of the other boards. 

After that it will depend on your ability to repair circuit board repair
Yep. I intend to remove the Ultra III as soon as the extended family clear out after this weekend (big Easter family reunion). :)
While the nieces were here, I successfully booted up Galaxian, however Battle Chess and Yeager's Flight Simulator didn't get past the initial disk reading stage. Those latter two games used some sort of copy protection scheme that I'm sure had to do with disk drive rotational speed, which may be off after all these years in storage.
My repair to-do list on this old machine is starting to look a bit beefy. But, it'll be worth it in the end. :) 

Thanks for the input.
