I have a dead IIcx and a working IIci. I found a Centris 650 online, but the case is destroyed. The pictures show the power light on - is that enough to determine if it has been battery bombed or not?
I got the computer and it actually booted but had lines on the screen. After disassembly, I found the battery had burst and there is some corrosion, but it looks repairable. After it dries we will see what cleaning yields.
