PSA to SparcBook 2 Users

Yea I received a Sparcbook 2 and saw this damage knock some SMD 
components off the entire OTHER SIDE of the board from the leaky cap.
Got it going again with cleaning and repair work though.

I had a SB3 fail in its power supply module due to shorted tantrums on 
the output side of the supply which cooked the coil and switching driver 
Luckily most of these components were available from digikey at the time 
and I rebuilt that entire supply rail and the system came up OK.
