You are involved in the design of microprocessors at a company infamous for being ----> The Firstest with the Worstest <---- To put it bluntly, Ken, judging on the basis of products shipped, the architectural design team at INTEL have their heads firmly entrenched anally. I am not surprised to see such a flippant response to a serious problem from an INTEL uP designer. The fact is that an I/O chip that can't tell you it isn't ready is a *BOTCH*, pure and simple. {ihnp4, dual}!ptsfa!gilbbs!mc68020 (Tom Keller) ^^^^^^^ /* *WHAT*? **ME** biased?!? */ (* we may not be big, but we're small! *)
