However, the SE for the most part comes with SIMMs that ARE faster than
required. A standard SE needs 150ns SIMMs, but normally comes with 120ns
SIMMs (some early SEs did come with 150ns SIMMs), apparently because of
quantity discounts on the 120ns SIMMs (the same ones as used in a Mac II, IIx,
and IIcx).
To avoid confusion, I would say to only get SIMMs that are 120ns or faster.
The slower ones may work now, but if you ever upgrade in the future...
