[comp.sys.mac] Another Mac SE/30 question - RE: SIMMs SE --> SE/30

Just make sure that you buy SOJ (surface mount) simms designed for the MAC II.
They are fast enough for the 16mhz '030, and can be used in ANY mac.

Wouldn't the SE/30 require the 120 ns SIMMS, same as the II, and not be able
to use the 150 ns SIMMs that the SE uses?
