that put the IP stack on board running from an 80186. Obviously, didn't
keep up with changing standards. It also had the problem the IP address
was tied to the Ethernet address.
I think this depended on the driver being used -- the EXOS has half a meg
or so of memory that can be used to run code on-board (potentially
offloading protocol overhead), but not everything made use of it. I have
one in my VAX 11/730 and it works fine under 4.3BSD with no weird
restrictions, but it doesn't make use of the onboard RAM -- it just
controls the board directly.
They seem to be pretty nice boards, but I've only played with the Unibus
version.

SGI used them in the 68K IRIS machines. There was a way to get to the
raw interface, which was the way they used them, or was it Integrated
Solutions...
There's stuff up on bitsavers about them.
