Sounds perfect! I would be very glad if I could get your program
and merge it with 750's boot stuff. The point: As far as I know
only 11/750, uVAX and 8200 reads in LBN0 from disk and executes
it. Other VAX systems (730, 780, 8600, 8800...) reads boot from
the console media and have no need for this low-level stuff in
LBN 1-15.
