Was an upgrade for ethernet TCP/IP for Unix V7 ever
done when running under SIMH?

Was an upgrade ever done for Unix V7 when running
under SIMH to read and set the date/time? I have a
work around but it doesn't work because when running
the sim it inserts boot code then when the 'run 2002'
is issued further startup commands in the 'conf' file are
ignored.

System was built from unix_v7.tm dated 20 June 2006.

run.conf contents:
echo

Yes, the BSD 2.9/10/11 stream include the UCB Networking stack - it runs
just fine on SIMH. In fact one Oscar's PiDP-11 [which used simh for the
simulator] its one of the systems that is automatically loaded.

Where would you read the clock? SIMH emulates real HW  - V7 was distributed
for DEC HW through 1979 on the 11 and DEC had nothing.
That said, could you create something sure - I bet you could.  Maybe the
easiest way would be to use a virtual DL/DC/DZ/DH serial port and have V7
read the clock from a 'serial line.' when it boots.  Then set up a process
on the SIMH Host system to source the data that V7 read.

That said, you probably could rewrite what you are starting in your example
to SIMH's expect/send command system to do something for you - but I'd have
to think about it.

FWIW: all those deposit commands should be unnecessary.  Just make sure you
have a proper boot block on the disk, as dmr tells you in the 'setting up
Unix' document in /usr/doc and SIMH can boot from the controllers.
