Yeah - Stratus rocked :-) The 'big battle' used to be between Non-Stops more 'software based' fault tolerance VS. Stratus's fully hardware level high availability. I used to love demo'ing our Stratus systems to clients and let them pull boards while the machine was running...Just don't pull 2 next to each other :-)

Also, I think Stratus was the first (only?) computer IBM re-badged at the time - IBM sold Stratus's as the Model 88, IIRC
