Tandy 600 is single side double density fat12 360k 3.5" floppy.
my backup copy was previously amiga format, so anything that doesn't believe the fat descriptor block and looks at side 1 is going to get very very confused.
It's a very good test case. 😀 Any code/hardware/firmware that tries to be smarter than the floppy disk, fails.
More #PocketChip goodness!
Hooked up the USB floppy drive and it worked for msdos 1.44M and 720K disks!
It mounted the Tandy 600 disk but it wasn't right and I wouldn't try to write to it.
CHIP kernel doesn't have Mac hfs compiled in so no mac hd disks.
As I'd already read, RISC OS doesn't like USB floppy drives.
The USB driver stack finds the device, recognizes it... and fails to present it to the SCSI system.
There's a replacement USB stack that should work, but I don't think it's really worth the trouble.
I don't have any Acorn disks around and even if I did these "pc compatible" - only devices can't handle the 2K sector size Acorn used. 🤗
