Mac SE Checkerboard pattern after cleaning battery leak

[GiGaBiTe]

Hi,

I've got kind of similar issue, do you know how I could "reset the cpu by hand" ? Apply +5V on RESET pin ?

Thanks

Stéphane

That's a good way to blow something up if there's a short to ground somewhere. Use a resistor, like 330 or 470 ohms to the 5v rail to limit the current.
