Here is an updated and corrected summary of my original question:
>I just received a SS-1 to SS-2 upgrade kit, and now I want to move my added
>(i.e., those beyond the base 8 MB) SIMM modules to the new SS-2 box.
>However, a neat little trick in the SS-2 Installation Guide is that the SIMM
>installation instructions, which previously (for SS-1s) were in an Appendix,
>have now been moved into a separate manual called "Installing SPARCstation 2
>SIMMs". Obviously, I don't own that manual, so I wonder:
>
>Would anyone offer me SS-2 SIMM installation maps (i.e., which SIMM sockets
>do I fill) ? I imagine that I still need to install groups of 4 identical
>SIMM modules. Do I fill the groups with the same symmetry as the factory-
>installed modules, e.g., should I add four modules in U0312-U0321-U0310-U0308 ?
I just received a summary of the relevant pages in "Installing
SPARCstation 2 SIMMs" (thanks a lot to russ@MATH.ORST.EDU <Russell
Ruby>), which is THE authoritative way to place SIMMs in the SS-2.
Note that this supercedes the incorrect information in my first
summary.

Now, the instructions, quoted from page 11 of "Installing SIMMs"
--begin quote--
You must install the SIMMs in unoccupied slots so that all slots
a memory bank are filled.
Memory bank 0 is ALWAYS filled. The SIMMs in bank 0 are used to
boot your SPARCstation 2.
Suppose banks 1,2, and 3 do not have SIMMs installed. You want to
install additional set(s) of four SIMMs. See figures 1-4 and 1-5.
You should install each set of four SIMMs according to the following
sequence:
BANK 2
BANK 1
BANK 3

I hope this helps all of you SS-2 owners out there !
