Is HDB-DOS fully compatible with Disk BASIC?
A. Virtually. There are some applications which either access the floppy controller hardware directly or use special copy-protected floppy disks. Those applications won’t be able to take advantage of the hard disk. But for the vast majority of Disk BASIC software, HDB-DOS will work just fine. Machine language programs that utilize the DSKCON routine documented by Tandy should also work without a problem.
