It's pure System 6.0.x. Nothing special about it. Same as everybody else's.
It has some A/UX stuff that the hoi poloi do not have (A/UX startup and
a bin folder).

Forget about making it useable. There's nothing you can do with it anyway.
Even if you make it 6MB it's pretty frustrating using a Mac with just 6MB
of disk space. Basically the Mac partition contains enough stuff to boot
A/UX and that's all. Use your other hard drive(s) for decent sized partitions.

You can see them from MacOS using SCSI utilities or from A/UX startup using
/dev/rdsk/c... special files.

Man pages are built in on the disk you have now. You might find the following
helpful: gd(7), pname(1m), dp(1m), and maybe some others.

What do you mean by "uniquely"? If Apple are sleazy then they are not the
only ones. And in this case Apple are not sleazy at all. The A/UX SCSI disk
driver is very generic indeed. It works with most 3rd party disk drives. Do
you mean HD SC Setup? Disk formatting software is drive-specific. You can't
expect Apple to support all 3rd pary drives out there. Impossible task. Apple
supports their own drives which is all they have to do. In fact, when it
comes to system software Apple is very generous. So is their support on
the net. I don't know anything sleazy about Apple at all. In fact, their
generosity is growing all the time - 1991 has been a great year for free
software.

It's not the questions, it's the insults that are the burden.

It can. It's just normal system software.

No. But if you want to mount a MacOS filesystem that is inside a partition
on a disk then A/UX must recognize the partitioning scheme. I presume that
this is what you mean. For the third party drive you must have a valid
A/UX partitioned drive to mount both types of partition. And so the disk
formatting software must create the right partitions. If it doesn't then
you might have to buy some other software to do the job. That's easy.
