Russ,

The problem you are having ("Internal Time Step Too SmaLL") is
unfortunately a very common one.  As the name implies, it has to do with
setting time steps when solving current equations.  The thing to do,
which works about 95% of the time, is to  set the option ABSTOL to 1
microamp (.Options abstol=1u).  Abstol is the absolute current error
tolerance with the default value of 1 picoamp which is a very small
value.  By setting it to 1microamp, you will sacrifice some accuracy,
but you will get the program running.  Also, you mentioned that you
initialized the internal nodes.  I don't know if you used UIC on your
Tran card or not; if you have, make sure you have specified  *all* the
nodes on your .IC card, otherwise you'll get the above error again.
Good Luck.
