The important word is "rated". No... Apple never rated the SE/30
for 16MB SIMMs, but various sources claim they work.

I have had that experience trying to use 64MB 72-pin SIMMs. The reason
it doesn't work is complicated but logical. Is is *possible* to
make a 64MB SIMM work in, say, a 660av, but most of the ones that
happened to have been manufactured have an incompatible refresh scheme.
