I would much rather use either emulated TU58 or real 9-track for installation. I think I would need to boot from TU58 in any case. But I don't have any 9-track installation media, and I've had no luck yet getting real TU58 tapes working. I would certainly be interested in getting my hands on probably-good TU58 and 9-track installation media relevant to my 11/730. I'm only expressing interest in the TK50 media (which I've also had poor luck with) because I haven't tripped over better options yet.
