Thanks to all who responded to my original posting.  I have read
TN 176 as recommended and I understand that Apple was unable to
predict the changes implemented in the 4 Mb SIMMs, but even if I
get 4 Mb SIMMs made of 1 Mb chips they will not work because the
MacII ROM "will not recognize 4 Mb SIMMs".  It seems to me this is
a ROM bug that has nothing to do with the new chip design.
Judging by the response, Apple has done an excellent job of
emphasizing the 'we can't predict the future' explanation and
playing down the mysterious ROM problem.
