[Coco] Reading/Writing Model I/III/4 Disks on a CoCo

[Luis Antoniosi (CoCoDemus)]

the default FLOPPY_DS80 from os9 build. Don't have it now. But I can format
a disk:

format 2 '80' "DISK"r

without any problems. Why the BASIC09 can't seek further than 34 ? And
about my backup.asm that had backup up correctly ? Seems to me there some
check inside Basic09 functions.
