[comp.sys.mac] SIMM's

seung@husc8.HARVARD.EDU (Hyunjune Seung) (03/08/89)

Sorry to clog the net, as I'm sure this question has been answered before.
How does one tell the speed of a memory chip?  I have SIMM's that carry
a marking of "-15" on them.  I assume that means 150 ns.  Can these be 
used in a Mac II?  If not, what can they be used for?

Yes, these are 150 ns SIMMs. They cannot be used in Mac IIs, or anything
that was introduced after that. This leaves you with Mac Pluses, or Mac SEs.
This does not include SE/xes. (sorry, SE/30 or whatever it's really called).

I am looking for the part number of National Semiconductor's 1M SIMMs.
Please send to me direct as I doubt it is of interest to the rest of the net.
Thanks in advance. - Yossie

P.s. an old net-address that seems to work is taux01!cyosta@nsc.UUCP
