Just finished recapping a CC yesterday and it wouldn't boot.  I resoldered any suspect points on the analogue board and checked the vias mentioned in here... Then I put a small 3V watch cell where the (dead) PRAM battery was... and it booted.  Yay!  This puppy is maxed at 10MB, i installed a spare 256 VRAM card and FPU.

Also Lazarus, you are missing the green channel completley.  I'd put it back to the "rosy" colour and focus on getting any hint of green to appear.
