Hello.
First of all, you need a copy of the CONSOLE cassette, that contains
microcode for the 11/730
(mine remained inserted in the drive for years and has a bad sticky
syndrome and black spots).
I have a VAX11/730 sitting in a depot, and a lot of TU58 cassette, with
various software, but
unfortunately no spare console or diagnostic cassette.
I would try to dump it, but unfortunately I don't have a TU58 drive unit
to read it
(I'm searching for one to buy since a lot of time, if someone in EU or
around has one, please let me know thanks!)
On this site there should be a copy of the CONSOLE:

Here some diagnostic for 750 (could work on 730 too?) and some software:

Falls somebody has something more, please let us know!
Thanks
