Sad Mac
A Sad Mac is a symbol used by older-generation Apple Macintosh computers (hardware using the Old World ROM), starting with the original 128K Macintosh, to indicate a severe hardware or software problem that prevented startup from occurring successfully. The Sad Mac icon was displayed, along with a set of hexadecimal codes that indicated the type of problem at startup. Different codes were for different errors. This was used in place of the normal Happy Mac icon, which indicated that the startup-time hardware tests were successful. In 68k models made after the Macintosh II, a tune (Chimes of Death) was played.
Models prior the Macintosh II crashed silently and displayed the Sad Mac, without playing any tone. PowerPC Macs played a sound effect of a car crash, and computers equipped with the PowerPC upgrade card used the three note brass fanfare death chime(A, E-natural, and E-flat) same as the Macintosh Performa 6200 and Macintosh Performa 6300.
A Sad Mac may be deliberately generated at startup by pressing the interrupt switch on Macintosh computers that had one installed, or by pressing Command and Power keys shortly after the startup chime. On some Macintoshes (e.g. PowerBook 540c) if the user presses the command and power keys before the screen comes up, it will play the chimes of death; the chimes are a fraction of normal speed and there is no Sad Mac displayed.

Famous quotes containing the word sad:
“Scepticism, as I said, is not intellectual only; it is moral also; a chronic atrophy and disease of the whole soul. A man lives by believing something; not by debating and arguing about many things. A sad case for him when all that he can manage to believe is something he can button in his pocket, and with one or the other organ eat and digest! Lower than that he will not get.”
—Thomas Carlyle (1795–1881)
