can you take a high resolution photo of the pcb where the battery explosion was?

the fact this SE/30 Rom gave you chime of death tells me your close!

i bet if you had a IIsi rom simm or one of dougg3's it would boot up.

but then again after reading this … the IIfx rom should work too..

i mean if you are hitting the power button and its coming on, that is half the battle.

the next thing you should hear this the start up chime.

if you don't get that then… usually a rom type thing… or ram.

if you turn it on and just let it sit with the monitor connected, does video eventually appear?

i do not think the Iici needs a pram battery to work.
