Early realtime variants of Unix.  I don't think it's correct to state
that MERT "never made it outside the Labs" -- wasn't dMERT ("duplex 
MERT") the original operating system for the multiprocessor 3B20 in
the #4 and #5ESS telephone switches?  Indeed, vestiges of this use
have crept into more modern AT&T Unix releases; for instance, there
are references to MERT system call and signal numbers in various SVR4
header files.

 objects that he could think of, and had screamed: "You lamp!  You towel!  You
 plate!" and so on.              --Sigmund Freud
