I seem to remember that those came in a couple of sizes: 64K each and 
256K, maybe? I may have some around, too, but I have to find the 286 
that the memory expansion card is in. These look to be the 64 K variety.

I had this 286 (with an Intel AboveBoard memory expansion card) running 
Minix and a web server. Sort of an exercise in minimalism for me.

There was also something from AST called a Six-Pack Plus or something 
like that that included memory expansion and took chips like this. I 
think I have dumped all my old, old ISA cards, but I'll take a look. I 
used to have a couple of them.

Nah, just looked and I must have purged them. It only takes one 
experience like this to keep me from throwing anything away for years. 
My wife doesn't understand my reluctance to part with things that I 
think I might be able to use... someday.
