Hi, I tried to boot my Macintosh Fat Mac (upgraded from original 128K. I’m the original owner) and the system disk gets ejected after a a second or two. My Mac does chime when powered up. Its been several years since I booted this Mac but it worked fine last time using same system disk.

The disk may have gone bad, try another boot disk. Use canned air to blow out the floppy drive. What faces or notices are you getting on the screen? Have the capacitors ever been replaced? You can get a new boot disk here: https://www.ebay.com/itm/Macintosh-128K-… UPDATE 6/9/19 I have sent a few boards to MacCaps with excellent results. Slow but very good service. http://maccaps.com/MacCaps/Repair_Servic
