Booting an old Mac IIsi
I'm sure this is a well covered problem, but I can't find the solution. We are trying to boot up our IIsi that hasn't been powered up for a decade or more. I replaced the battery with a fresh one, and while there is power to the computer, nothing more happens. I get a flash on the monitor, so I know something is alive, but I suspect the PRAM or whatever has been wiped.
Is there a set of steps listed somewhere to see if I can get this booted?
Thanks,
Rick
