Scitex NuBus card ID?

[r.stricklin]

I just picked up a Scitex NuBus card at surplus a couple days ago.  
Anybody have any guesses what it is?

The only connector on the card is the DIN96 NuBus connector. There  
are two sets of empty pads for 96-pin connectors (4 rows of 24 pads).

Major chips include a Cypress CY7C342 EPLD, 40 MHz Motorola XC96002  
DSP, and a custom LSI QFP marked "COLOR-SCITEX". There are a fair  
number of RAM devices, too, including MT5C1008 20ns 128Kx8 SRAM in  
one group of 8 and one group of 5, MT42C8256 70ns 256Kx8 DRAM in one  
group of 8, and four CY7C199 35ns 32Kx8 SRAM chips.

Silkscreen marks include SCITEX, "S.C.N. II", "ZEN", "PS QUAD", and  
"QUAD CS".

Stickers include "NURIT" and "VS500048/ 5".

Guesses? The only Scitex card for Macintosh I can even verify exists  
is the ResoLUT, which accelerates color space translations. Not sure  
though if that's what I have.

Any ideas?
