Johnny/Ronny, et al,
the vector is just that - from PDP11 speak, the Interrupt Vector >>the
location that an honored devices' interrupt (priority interrupts were
new to minis then) level pointed to (or the location that held the
interrupt service routine location).

That is how I think I can explain it from the 11 perspective.

My status on my klutzy PPPD problems.

I am just finishing an install from NetBSD CD.  I have just finished
building all hte devices, and am getting ready to check for login on the
dhv port 0.
It is built as ttyS0, with an on status in the ttys file.

Now my dumb question cause I really am getting skittish and nervous
here:
Which way does the bulkhead cable assembly plug into the board?  There
is a red stripe, I thought that went to pin A on the connector on hte
board.  BUT looking at all the other flat cables in the uVII, the red
stripe seems to be down.

SO. if i put it in backwards, I can (with my luck) kill some drivers or
smoke the board. And I probably won't get a long in prompt from a dead
board.

Thanks for any help!
still pushing this puppy!
