Unfortunately, the 30-pin SIMM could only have a maximum size of 4 MB,
so a 72-pin replacement was cast down with a maximum size of 16 MB:
Now the 72-pin SIMM could give most systems up to 128MB of total RAM
when four were installed, but even the fastest EDO models were only as
fast as 60ns and thus easily caught and devoured by the hordes of Windows.
So, a 168-pin DIMM was introduced as superior replacement allowing over
128MB per unit and allowing for systems to have up to 512MB of RAM at a
screaming speed of 10ns or less:
