What is this card and what's its purpose?

Question

I've come across what appears to be a vintage PCI card for the Macintosh. I've searched everywhere to find out what it is, but so far it's been unsuccessful. It has what appears to be memory sims and at least two FPGAs, but has no external ports, making it unlikely to be a conventional graphics card. It's labeled as PowerShop Mezzanine and possibly made by Adaptive Solutions. The board was copyright back in 1995, placing it around the PPC era of Macintosh machines. Any information on this board?
