I have been trying to get ADTPro working now that I have a good working Floppy drive.
Both Audio connection and SSC connection has the same issue - garbage text after the first couple files listed when doing a remote directory.
I can send data fine, I have even sent a copy of a disk back to the computer and ran it in AppleWin. Using the DiskServer website, i can send disks via the audio connection. Just not with ADTPro.
Terminal mode on the SSC Works, i can send data back and forth. I can Boot strap no issue, just once it gets into the program i start getting garbage on the screen.
I have tried two different laptops, two different usb/serial adapters with different chipsets, linux, windows XP and Windows 10. same isssues.
I am thinking it is something with the Apple itself now, but can't begin to guess what would be common between the audio and the SSC connections.
