thanks for the info, but there must have been something more serious wrong
with the atari, because when I plugged the new adaptor in and turned on the
power I heard a crack and it started smoking - seriously. So tomorrow I will
be driving 2 hours to return it (I know its silly, but I want an atari! plus
I can pick up some more carts)
at least my stella programming is going better. I hope to be able to post
something here soon.
