[Oberon] A2 on VirtualBox

I have installed a version of A2 from an old iso image onto VirtualBox.
 The file dates on this image are Feb 19, 2009.

This image boots in the VirtualBox environment, and installs.  There is an
ASSERT that fails in the AM79C970 NIC driver.  When I defeat that ASSERT,
the IPv4 network operates.  The IPv6 network installs addresses, and other
ipv6 machines on the same local link show the A2 machine as a neighbor, so
some correct packets are leaving the A2 box, but I don't make any progress
beyond that point.  I am able to Ping.Ping the A2 box on itself by 2
different v6 addresses.

test1f.link.vima.austin.tx.us  does respond (local address)
a2.vima.austin.tx.us  does respond (global address)
localhost.vima.austin.tx.us  fails to respond (::1)

I thought a current version would be a nice thing to install before I
investigated further.  I have downloaded the svn 4281 image from the Google
mirror.  This image appears to be starting up, but the resulting screen is
totally black.  I have not set up any monitoring on the serial port.

I wonder if anyone has used the 4281 image in virtualBox.
I wonder if anyone has anything like a packet sniffer in A2 so that I can
look a little deeper into the IPv6 situation.
