I remember seeing NT3.5 running on an Alpha at a trade show around the same time period. A higher end model than the one the author posts here. The reason why it never found "consumer success" is that in late 1993 dollars it cost $7800 , equivalent to about $13,600 today. When at the same time it was possible to buy a 486DX/33 for just under $2000 in a pretty decent, though not nearly as capable configuration. That is what consumers could afford.
