Hi Mark,
Under V3.9 this works.
The first VAX is configured as a 780. The config file is:
set cpu 128M
set dz lines=8
attach dz 5100
set rq0 rauser=4096
attach rq0 /simh/vax/rq0.dsk
set rq1 disable
set rq2 disable
set rq3 disable
set hk disable
set rl disable
set rp disable
set ry disable
set ts disable
set tq disable
set tu disable
set xu enable
set xu mac=08-00-11-C3-56-B4
set xu type=delua
att xu0 eth0
set cpu conhalt
set cpu idle
d wru 6
b rq0
The second VAX is configured as a 3900 and the config file is:
set console brk=4
load -r /simh/vax/ka655x.bin
set cpu 256m
set dz enable
set dz lines=4
attach dz 5104
att nvr /simh/vax/nvr.img
set rq0 rauser=4096
attach rq0 /simh/vax/rq0.dsk
set rq1 disable
set rq2 disable
set rq3 disable
set rl disable
set ts disable
set tq disable
set xq mac=08-00-11-C3-56-39
set xq type=delqa
att xq0 eth0
set cpu conhalt
set cpu idle
d wru 6
d bdr 0
b cpu
I upgraded the pcap development to the latest version and the VAX simulators now simply report that eth has been connected to device tap0 although none is configured. They do not communicate over the eth device.
I configured tun/tap and changing eth0 to tun:tap0 the 780 simulator boots and joins the cluster using the Alpha on eth0. If I drop the 780 and boot the 3900 it boots using tun:tap0 boots but does not see the cluster.
If I try to bring both up the first node is OK. The second node reports that eth is busy. Adding a tap1 for the second node does not change this.
Regards
Dave

Thank you, Dell, and Sandy Strain, both of your responses were EXTREMELY helpful to me, and these all worked!
Do either of you have any additional thoughts about how I could make what I believe to be a bootable file (extracted from a Microtech/Point4 QIC tape) into a bootable device for the Nova?
I'll start with the Minicom Disk To Tape Utility:
http://microtechm1.blogspot.com/2015/09/minicom-disk-to-tape-copy-utility.html
I've attached a .zip of the binary file that I extracted from this tape for reference. It's very small, so I zipped it up only so that the emailing process didn't interfere with or reject it.
Thanks, all!
