Is it possible for a macintosh to recover from a Sad mac without having to be forcefully restarted?
Also, Is it possible for new world ROM's to get sadmacs?

Re: Sad macs.
The sad Mac startup icon was used in 68k and old world PPC Macs. It indicated a severe problem that prevented startup, usually a hardware problem. It was accompanied by error codes and/or special sounds that came in place of the normal startup sound. On later Macs only various sounds were, and are, used to indicate a problem that prevents startup.
No, you cannot recover from a sad Mac without restart. Usually more than a restart is needed to first solve the underlying issue (like loose RAM).

Re: Sad macs.
The one sad mac that can be triggered and easily recovered from is the "0F00D" error, which can be triggered by hitting the interrupt switch during first disk access. A soft reset will fix this. This error can also occur when the floppy cable is loose, or a hardware component of the floppy system (either the drive itself or the on-board controlelr) is damaged.
I'll echo Ronald though; sad macs were used on old world Macs as a way of identifying a hardware issue; usually the hardware needed re-seating or replacement to fix the issue.

I think the only time I saw a Sad Mac in person was when I tried to use the startup floppy from an ancient Mac Plus (I think it was System 5) in an LC 475. I don't know what the technical details are, but at least the problem was solved just by removing the floppy and rebooting.
