I was using one in a C610 for a while, and it worked perfectly.  The 
performance of the 40Mhz Centris 610 was about the same as the 
overclocked 40MHz Centris/Quadra 650 that I'm using now.  I figured that 
the Sonnet card would be a slower than a "real" 40MHz machine, since it 
is a clock-doubling card, but the difference was minimal.  If anyone 
cares, I can dig out the Speedometer results.....
