I was an analyst who covered the server space but I sort of lost track of the details of Tandem FT latterly even though I knew the head of HP enterprise server pretty well. As I wrote, a classmate. Originally it was 3 hardware modules voting but that changed latterly and I forget the details. NEC had something as well based on standard hardware as I recall.
