Nothing like having a son with the skills to fix ancient hardware! Would you please keep me in mind if Adam is able to get your Mac running - whenever that is?<br>
<br>
FYI to others who responded to my original post. Thanks for your comments. These 5.25” floppies were created on an Apple IIc and it did have an internal 5.25” drive that stored (I believe) all of 140 KB! This computer pre-dated the Mac by a few years and served us well in the early 1980s.<br>
