OK, I basically have that except the tape is swapped with the network
card.

How low a priority can the serial card go, if all I want to do with it
is output to a serial printer?

And my card cage reads from left to right.....(:+}}...  But, I understand
where you are going.

Ohh, that is good to know.  I will try that and see how it goes.
A full tape dd/dd/tarset of 1.3.2 only took about an hour to write,
so that is not all that bad with the tape/ethernet reversed.

I am trying to find a PDP-11 for some 2.11BSD.   Maybe, if I get real
lucky.....(:+}}..

Also, I want to try a VAX 11/730, sometime, if I can scrounge one of
those locally.

What is the status of any VAX 11/725 port of NetBSD?

Thanks
