Hi,
I just recently obtained LC III with Apple IIe card.
I got it running and managed to transfer some of my old Prodos 3.5 and 5.25 disks to the HD Prodos partition.
My problem is that when transferring files downloaded on eMac with USB disk drive, none want to work
on the Apple IIe. Unfortunately, the manual for the card is too old to cover G4 systems 
I need help on how to download the files on eMac and then transfer them via 3.5 disk to LC.
Thanks in advance,
Your USB 3.5 inch Floppy drive cannot format the disks in 800kb GCR format the drive is incompatable withe the IIe drives.

I am aware that I can't make PRODOS disks with USB drive but my question is about transferring files downloaded on eMac to LC so that they can be used with Apple IIe card. I can use LC to make disks for use with PRODOS.
