Very likely true. The original KL10 doc clearly says only one NIC is 
supported. I just try my best to keep my DECnet and IP subnets isolated

Never seen or logged into a TOP-20 system ... as you say below, curious 
about what it looks like. Anyway, have a Panda release up now, working 
through tips for the basics.
