  There doesn't seem to be much on this card. It is possibly part of the "Star" or "Star Lite" publishing system by Scitex. The Scitex site has four text notes on microchannel adapters, all Y2K related. That's it... 

Greg Chabala sez:
   I think what you have gotten ahold of is the Scitex FiberChannel card. Scitex used PS/2 model 80s and still uses 95s as workstations for running their "Dolev" line of film plotters. Star is one of the software versions. This card would talk with the Dolev through the fiber optics, while the PS/2 would have files passed to it for plotting over a network. The card should only operate when running the Scitex software, which is a custom GUI running over an old version of AIX. (Ed. AIX for PS/2? ver 1.1 to 1.3?)
