Accelerators, array processor ?

[Delman Lee]

I am interested in add-on boards (accelerator, array processor, etc..) for
Sun workstations. I have heard of 2 boards for VMEbus --- SKYbolt from SKY
(80MFLOPS), and SuperCard from CSPI (80MFLOPS/card). 

Questions:
- Anybody out there using these boards? Any comments on them? 
- Are there any add-on boards for SBus?
- Any other boards of same category?

Thanks --- Delman.
