  1. 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.

  2. 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.

I thought it would be some leaking capacitors like many macintosh of this model have, I was ready to recap boards. But it's not. 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
