... and IBM owns a large chunk (all) of Stratus.  Their scheme employs 
fully-redundant, "hot-backup" voting pairs of 680xx processors -- no processing 
gain is attempted through parallelism.  They were formed by a bunch of Multics 
aficionados, who wanted to see that system run on a micro, and instead of 
making another "me too" supermicro, they targed the niche field of 
fault-tolerant computing.

I used to work for the competition (Tandem).  Tandem uses a software/hardware 
approach to fault-tolerance, that provides a performance increase through 
large-grained distributed processing when all processors are healthy.
