If it's EDO, it may not be compatible with systems that weren't
designed for EDO, and since none of the 16-pin parts were EDO, I'd
avoid it.

"Normal" and FPM memory stops driving the data output when CAS is
deasserted, regardless of the state of RAS.  EDO continues driving the
data output even with CAS deasserted, unless RAS is also deasserted.
