The majority of the responses are of the opinion that mixing 60 ns SIMMs
with 70 ns SIMMs will not cause a problem. Almost everybody suggested that
I either increase my swap space to 2 or 3 times the memory or change to
lazy swap mode, or both. I'll probably increase my swap space and go back
to lazy swap mode.
