We have four Mac IIs and a Mac IIcx and are going to load them up
with memory.  Are there any limitations on the speed of the SIMMs
we buy?  I assume we can't mix and match 80ns, 100ns, and 120ns
chips.  Also, can we take 1MB SIMMs out of the IIs and put them in
a Mac Plus?  Are there any speed limitations (or other limitations)
to doing this?

Thanks,
