When I worked for the Humungous Insurance Company of Hartford, CT in the 1980s, we were a beta site for MDF. The flexibility it provided was very beneficial to us. We didn't see issues with overhead, but perhaps it simply went unnoticed. Amdahl was always willing to wheel and deal so had we seen degradation we could have requested a discount. I don't recall hearing this was an issue for other potential customers, but it was a long time ago . I always considered MDF to be a real game changer. Later we were a beta site for PR/SM when IBM played catch-up. We had very good luck with Amdahl processors up to MVS/ESA which they supported a couple of years after IBM. We subsequently had serious performance problems with the 5995 processor. That pretty much was the kiss of death for Amdahl.
