From another (non-Hsu) IEEE abstract:

"Now it has the ability to calculate 50 to 100 billion moves within three
minutes." (Deeper Blue)

That puts the number between 277M and 555M NPS. I think this range is probably
accurate, because it should be easy to count the positions you search per move,
and this seems like something they might have done.
