My mistake. I'm not running V4.0, I'm running <span style="color:

</span>After posting, it dawned on me that I should have tried SIMH
V3.9.0, but it fails to boot:<br>

2..
-DUA0
1..0..
HALT instruction, PC: 00004C02 (HALT)
sim>
</pre>

I'm not sure why. I'm using the KA655x.bin that came with V3.9.0 and
a new nvram.bin file, but everything else is the same as the V3.10-0
RC1 instance.<br>
<br>
I just downloaded the current GitHub sources and compiled them (<a

losing connection to the cluster.<br>
<br>
I also should have mentioned that this dedicated Ethernet card is
plugged into the same switch as all of the other cluster members, so
that <i>shouldn't</i> be an issue.<br>
<br>
Thanks.<br>
