I scored an early Macintosh at an estate sale this weekend and I've been having fun messing around with it. It's a very early model without the 128K on the back, serial number F4190QJM001. I have 4 disks, the system disk, tour disk, MacPaint and Microsoft BASIC. At first the system disk would just eject, the Macpaint disk would work fine, the tour disk would kind of work after you had already inserted the Macpaint disk and BASIC wouldn't work. I took the computer apart (it had been apart before and has light pry marks in the seam of the case.) I accidentally damaged the drive in an attempt to clean it but I had a similar one that I bought years ago. Both are Sony and the damaged one is a model mp-f51w-03. For a few minutes the new one worked great and all my disks functioned properly, then it stopped reading disks and just ejects them. I have an external drive M0130 that appears to have an older floppy drive in it that also worked great for a few minutes and now won't. Is something killing them from sitting so long and then being used? Something else I can adjust or fix? Also interested to know what has been upgraded. I think that is the original motherboard that has been modded to 512K.
