Mary,
      The AT&T RAMDAC (ATT20C478A) is exibiting bizarre behavior; AT&T
has promised to have someone who knows the part call me.

      In the meantime I thought I'd try the Brooktree part so I called Rex.
Yesterday they told me he was on vacation and would be back today. Today 
they told me he was on vacation and would be back on the 13th. They didn't 
say what month.   

      Would you do me a favor and see if you can get some parts for me this
week? I am under a lot of pressure to turn this board over to programmers.
The part is Brooktree Bt478KPJ35 or Bt478KPJ50 or Bt478KPJ66 or Bt478KPJ80.
I need at least three.

      Thanks,

       Jed
