   Nope.  The C90 is a much older machine, first shipped in 1990 or 
1991.  The T90 was the first one to top it performance-wise, though, at 
2 GFLOPS per processor.  The C90 cranks out 1 GFLOP per processor.  The 
J90 was intended as a lower-cost (starting at ~$300K for a minimal 
uniprocessor config), lower-performance (CMOS, air-cooled, 220V, no 
MGs, no heat exchangers, etc) machine.

   (And for all you x86 overclockers out there who might turn your noses 
up at those numbers...these figures are for what your Intel processors 
would call "double-precision". ;))
