NB: Disk ROM is actually *FIRMWARE* not hardware, and cannot be directly
accessed thru nonstandard entry points because it changes between versions
(even minor revisions).

Right nowadays. But back in the 80s a floppy track based "multitasking"

the Amiga) would have justified direct floppy disk access.
Clean and within spec, of course. With true timing and no dirty busy-waiting.
