Re: "We know yields were bad and got a lot better. So by end of 98 they may have been yielding in the 160 DPW range."

Don't forget the .35u wafers early in the year in your calculations.

Kash,
There are 300 K6-2 (345 K-6) possible good die/wafer. At 60-70% thats 180-210/wafer. That's unbined. Then there is binning and final testing/packaging. Probably lose 5%-10%. Based on your 60% figure which I won't verify, that leave yields in the low 50 percentile or 160+ good chips/wafer.
