In my preparation for future growth in SPARCstation 1 memory, above the 16
Meg limit with 1 Meg SIMMS, I prepared the following chart to help us all
with this growth.

It's been my experience that at least two banks of four SIMMS slots have
to be populated, even if one bank is 4 Meg SIMMS.

It doesn't seem to matter which bank is filled next.  They can be filled
in any order, only 4 SIMMS at a time.
