  Mr. Macintosh is probably not in any ROMs except the original 64K set.
There's another interesting icon hidden in the 128K (Mac Plus & 512e)
ROM; here's a short routine that displays it:

PlotROMIcon(inRect)
Rect *inRect;
{
  asm {
       BRA.S    @2
@1     DC.L     0x40E132     ;address of icon in 128K (Plus) ROM
@2     MOVE.L   inRect,-(SP) ;was PEA
       PEA      @1           ;push "handle"
       DC.W     0xA94B       ;_PlotIcon
  }
}

  We've had Mr. Macintosh, the 'stolen' icon, the SE Team Slideshow...
I can just imagine what must be in the new 512K ROMs! :-)
