Hello all,

Earlier this week a Macintosh IIci arrived from Ebay that was described as having 'some corrosion on the power supply and motherboard'.

I stripped the Mac down to check the the logic board's damage: a red Maxwell battery had leaked (thankfully the Mac was used on its side so the case bore the brunt of the acid damage) in such a way that the battery holder became detached from the logic board.

Other damage includes a few corroded components such as the ROM pins nearest the battery.

Also included was a IIci cache card, an E-Machines video card and a Farallon Ethernet card.

As a matter of course I washed the logic board and recapped it with eight 47uf 16v and two 10uf 16v capacitors.

When I turn on the Mac the power supply kicks in and the hard drive spins up. The green light on the logic board comes on.

But there is no chime! I think the battery leakage could have damaged the ROM.

I have tried a SE/30 (chimes of death) and IIfx (normal chime then chimes of death) ROM in the IIci but it did not work.

I cannot get anything to show up on the screen.

Any suggestions would be much appreciated!
