I always use 9 chips in sunstuff.....(doesn't everyone?)... (:+}}...
Although I have heard some 3 chip stuff works.

After some hectic webcruising, I finally found the reference page
I was looking for.... alas it is in Japanese or the html is screwed.

Anyway, if I am reading the figure correctly:

  http://www.portnet.co.jp/JIS/techical/WS/sun4_75.html

shows the ram cycling by fours in the two rows of chips.
My machine seems to have 0 and 1 filled in each bank, with
3 and 4 open.  IFF I am interpreting how the sequence cycles,
I need to install all four 3 bank locations first, which
is a little different from what you seem to be suggesting,
and then add the 4 bank locations second?

Can someone confirm that?  I don't want to muck up the ram
positions.

The SS1 (4/60) seems to be entirely different from this (SS2 or 4/75).

Almost confusing, and a good reason to have the actual FEH diagrams.

Also, IFF I am out of 4 meg simms, can the last row of bank 4 simms
be filled in with 1 meg simms, or will it require 4 meg simms?
The IPX, for example can mix and match, but it requires the high
density ram first.

Thanks
