On the Inmos seminair in the Netherlands Inmos claimed a floating-
point performance ~1 Mflop for the T800. It is a T414 with microcoded
floatingpoint on a single chip. The chip is pin compatible with
the t414-20. We have't received the handout. I do't have the
exact numbers. They claimed that you can get samples within a few
weeks. Has somone worked with this chip?
