<http://pbs.org/plweb-cgi/fastweb?getdoc+pbsonline+whatson+7010+0+wAAA+Tilden%26%28Tilden%29%3Ahomepage%26%28Tilden%29%3Astation>
The page asks that you look up your local station listings & also gives
links to your local PBS stations. The overall Scientific American
Frontiers prog. is described at:
http://www.pbs.org/whatson/1999/fall/sciamerfront.html
Check it out.

thepast with good luck.
I have an aplliance repair place by my house with a bunch of old ovens and
such rotting in the weather in teir back lot.
Can someone point me towards a tutorial or "how to" for the OTU?
I have no idea how to use em, or if there is a specific one in which you
guys use.
Are they small enuff to incorporate pager motors?
THANX!
