Interesting puzzle. My first Ultrix was 1.1 on an 11/730 (I had prior
experience with 4BSD on an 11/750)

STABACK for the 730 was 3 or 4 TU58s, with the command parse table on the last
tape,
When I typed BACUP, it would spend about 5 minutes running the tape forward and
rewinding until it concluded there was no such command…
After the TU80 was added, I could boot from the RL02 and backup the R80 to t

FWIW, the 725/730 was somewhat unique in that the micro store was entirely

First of all, thank you very much to Mark for finding and fixing the uba
problem with the 750. Glad that modern Ultrix now works on that simulator.

Except for the VAX vector instructions... which GEM/Fortran knew about.

Consider this:

Bill,
What EXACTLY are you trying to do? What are you trying to do with the VAX/VMS
system?
What is the host OS the simh instance is running under?

Yup. Correct IP.
I ran tcpdump on the network and it's not responding to arp addresses from
the MAC address that VMS changes to.

The latest simh code at on github now will run Ultrix on the VAX750 simulator!
