I've got an old IIe that's working in mint condition. It currently has 4.25" drives and I want extract many of my old files to a newer computer. I'm thinking of acquiring an old 3.25" floppy drive to transfer files, then moving files to my PC. My question: if I get an old 3.5" floppy drive, do I need a new controller card or will it run fine on the 4.25 controller? Thx! Dale
