Is it true that Macintosh Plus ROMs won't work with some third-party<BR>
SIMMs? I bought some 1MB NEC SIMMs and get consistent &quot;sad Macs&quot; when I<BR>
try to start the Macintosh Plus with them installed.<BR>

  <div class="attr SUMMARY">
We don't know of any reason to upgrade ROMs for SIMM compatibility, nor of<BR>
any incompatibility with the mentioned SIMMs and the Macintosh Plus. If<BR>
the Macintosh bombs only with those SIMMs installed, try them in another<BR>
Macintosh model to see if it is related to the Plus or if one of the SIMMs<BR>
is bad.<BR>
