We have been using the QuickCard from CSP Inc. (40 Linnell Circle,
Billerica, Mass. 01821 [don't have any phone #]), costing about $10K.  It
has served quite well.  It is quite fast and easy to use under SunOS.  The
software version we have supports SunOS, Motorola SYSV68, and a couple of
other UNIXes.  I also modified the software provided by CSPI to drive the
QuickCard in a VMEbus embedded system we developed.  It is well suited to
performing FFT's, correlations, convolutions, trig and transcendental ops,
and general vector arithmetic.  Except for one slight firmware problem
between releases, we have had a good experience with it.  We have used it
only in a Sun 3/260, not a 4/260, and our embedded system.
