Re: Wanted: LM-709 (Spice model) National Op-Amp

Paul,

The name of the program is LTspice/SwitcherCAD III.

More non-sense. Users can import models and since LTspice
knows most Pspice and hspice syntax, it can even run the
imported models without modification. LTspice's SMPS
products are models in a HDL that can't be run in other
SPICE programs because the HDL is above their heads.

Opps, I was thinking of Tom Gross, the apps guy, who works
in a somewhat closer capacity to Tim Regen, hence I jumped
to him instead of the guy that doesn't work here any more.
Bill Gross was an op amp designer and then VP of that group
that knows little about SPICE and nothing about LTspice.
Yes, do pay him my compliments and mention Boeing SPICE.
He'll tell you lots of non-sense about SPICE.

You were at an Arrowfest and somebody said something. Wow.
Most physical simulators solve a matrix, that doesn't
make them varients of each other, it just means it's trying
to solve something. I would suggest that you don't dissertate
on topics that you aren't familiar instead of posting
garbage.

Yes, the people that sell the Webbench thing to National
told me that too. I laughed and walked away.

Thanks for posting this. I suspected that the Lederhosen
story wasn't true. I find that as my fame, for lack
of a better term, evolves, that there's ever increasing
strange storys about me that never happened or quotes
from me that I never said. The time will come when I'll
join Pease and not read Usenet posts anymore.
