The machine type was 6611 and there where three model, the smallest was
based on a 7011 the mid size one was based on a 7012 and the largest was
based on a 7013.
The base card is an Artic 960 card which is just a processor card with
some memory that gets an application loaded on the fly.? The top
interface card has a lot to do with determining what the function of the
card sandwich is, there should be a X-Y type code on the back of the
card that would define the interface.? They where used for all kinds of
things like Synchronous communications, X25 and network accelerators.?
Some of the interfaces cards used in the 6611 where unique to it and
never made it to the "standard" RS/6000 line.? There was also a PCI
version of the Artic 960 but by the time it came along the 6611 was long
gone.

So, what is
this i960-based card for?
They were the routers. At the core nodes of the network,
there would
be a big RS/6000s (very early POWER1 types) that would each do about
4-5 high speed interfaces (FDDI, HSSI, and 10base2). Each interface
was one of these cards, so each of the big RS/6000s would have about
4-5 of these cards.
IBM tried to commercialize the design, but it was doomed - the routing
engines were very fast, but the internet quickly outgrew the
architecture of the engines, and they apparently needed a complete
redesign to compete. IBM did release very few of these RS/6000s to the
public (I think RS/6000-320Hs with a fancy tag - machine type 6767?).
I have only seen one of these routers in the wild, but most of the
real NSFnet ones (I was decommissioning them, one time with a Sawzall
because of some live tangled cables).
Could it be related to what you
say in your post?

Possibly related, but that card is not one of the NSFnet
ones.
