My Macintosh Plus has many hardware issues, but I would like to address this one today. This checkerboard appeared one day and alongside that, the sound stopped working. I already replaced electrolytic capacitors on both logic board and analogue board. I recently upgraded my Macintosh from 2.5Mb of RAM to 4Mb of RAM and the checkerboard changed.

Hi there, I have got a macintosh classic with a broken motherboard. It gives horizon lines and doesn't boot. I have tried a lot. I have cleaned the motherboard with alcohol, I have cleaned it in soapy water, I have replaced all capacitors, I have checked the traces and contacts, all with no succes. When I got this mac it had a bad battery leak but thankfully no traces were erased but I think (having tried almost everything) some chips got effected by the battery acid. What else can I try other than replacing the motherboard? All sugestions are more than welcome! Thanks, Luuk.

Actually no capacitors have leaked, it's the PRAM battery that opened up completely (litteraly). The analog board seems to be fine but the mainboard has been corroded so much that the battery holder has desoldered. I've tried to clean up some of the corrosion with isopropyl alcohol but there's still a
