As I understand it there was no 'standard' format for ST-506/ST-412

to do it didn't work (different brand/model controllers).
I suppose that it the PC MFM controller used the same chip that the
AT&T 3B1/UnixPC used you would stand a chance, otherwise,
doubtful.
Anyone care to confirm/deny ? Also, don't know anything about the file
system, but if it's a common
one, you could potentially (and carefully) install the HD into a linux
box, mount it, retrieve /etc/passwd, and crack the sucker. With
today's machines you might be able to brute-force the keyspace, or
worst case, put a pretty good dictionary attack on it.
Am I smoking crack, or do the "mount it on a PC" answers ignore the
fact that it's an RLL drive? Doesn't that mean that a PC is not going to
handle the 7300's low-level format?

You could of course use a standard RLL ISA controller WD and others made
them when RLL was hot.
And even a 486 out runs a 3B1 several times. But there are of course lots
of P1/P2/P3 systems with one or 2 ISA-slots witch can be used.
