We do a Pentium III 800 MHz in the classroom. Scott added memory to it and
that seemed to help quite a bit.  I'm waiting to see if it turns out to work
ok or be the computer the kids fight not to get.

Does that mean you got audio to work well on other systems?  Have you
been following the audio work? I've seen a lot of emails go by and
some of them seemed optimistic so I'm hoping things might be working
soon. So far I;ve not even been putting Tam Tam on the
sticks because audo has not been reliable at all.  Which I agree is a very
big disappointment.  The Tam Tam suite is wonderful!

Thanks for your help with this.  Anurag is going to try to compile a list,
probably in a google doc, of what hardware we have and what performance time
we are getting and then we'll also record is kids favor or avoid it.  Maybe
you can add to this list.  It would be good to be able to give deployments a
clear idea of what is good enough.

Cheers,
Caroline
