Today, I got a Plus power board by accident, but after the power was powered, it made a daedo sound, and it could not start normally. Experienced friends can I give me to teach how to repair it?
My Macintosh 512K turns on with two pops ~ not a normal startup chime. After booting up, the floppy drive screen will be displayed, and some vertical lines will appear on the screen. Will change, has anyone encountered the same situation and solved it? This vertical line did not appear...
