And the HD-Port is not useble for other devices (tapes or the like).
They just provide the signals the OMTI wants by software. They do not
use the adressing sheme and protocol Atari defined for the HD-Port.
So it is not compatible with *any* software that does adress the HD
directly (not via system calls).

It is bootable by now (with a ROM patch).
