Yes, but no...
National Semiconductor has a board that can handle up to 16MB, but I don't
know if it can take 256K simms.

In any event, you probably don't want to do this. The money you spend on the
board could instead go to 4MB SIMMs. Furthermore, access to that RAM would go
over NuBus, and would thus be _slow_ compared to regular memory. (I seem to
recall a minimun 300ns access time, though I'm not sure. That would make it
about 4 times slower, although you might make some of it back on wait states
you wouldn't need.)

Tech issues aside, the economics of the situation pretty much rule it out,
I think...
