So, there's a Mac Classic that was dropped off at
my friends' store
(otherwise headed for the skip/dumpster) and I "rescued" it. Yes, I used
quotes, as there was this "weird" bright yellow and purple goo emanating
from the unit.
Thinking something completely odd was spilled *into* the unit, I took it
apart to find the damage. Turns out, the PRAM battery was in such bad shape
that it was the source of both the purple (rust & other dissolved metals)
and yellow (still not sure what that is) goo.
I had to pry the motherboard out of the unit (slightly destructively) due to
the corrosion on the rails on one side of the motherboard rails just to
remove the motherboard. Whatever was bent can be unbent, but will need a
*lot* of cleaning to refurbish.
The contacts for the PRAM battery were completely gone on the (+) side, and
gosh-darned near gone on the (-) side (enough so that it couldn't be
repaired). I removed the PRAM battery & holder (with a pair of pliers as it
was also damaged to an unrepairable state).
That said, what do I actually do with the thing? My idea: Disassemble the
unit and turn it into a 68K "microcontroller" trainer unit with a
recent(ish) Flash ROM and Static RAM. Yes, I have the technology to build
that. Or... back to the original destination (bad).
Anyone want it for price of shipping?
And yes, for those "keeping score" I have now built a "Mac Cracker."
Do I
get a prize for being the "Last Geek Ever" to build one? ;-)

TBH, the Classic was a bit of a "road apple" when it worked fine.
