gEDA-user: Spice Jfet Model Strangeness

[User Tomdean <tomdean@xxxxxxxxxxxxx>]

I know little about jfet's.  So, I started playing with a model I took
from onsemi.  The only parameter I can match to the datasheet is VTO.

I tried dc v2 -1 1 .1 and looked at v1#branch and v2#branch.  Not what
I expected.

So, I think I am doing something wrong.
