Maybe even a hex dump of him. 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! :-) -- ========== ....... ============================================= Ken McLeod :. .: UUCP: ...{spsd,zardoz,felix}!dhw68k!thecloud ========== :::.. ..::: INTERNET: thecloud@dhw68k.cts.com //// =============================================
