Question: Why does NeXT use 100ns memory, when, for example, a MAC IICI requires 80ns memory and most other workstation manufacturers use 80ns or 70ns memory. Did NeXT add wait states to make this possible? Did NeXT forgo improved performance just to save a few pennies by buying slower memory? Tim Van Zandt tvz@princeton.edu

Tim Van Zandt tvz@princeton.edu ---- Well, I'm guessing here, but if I recall correctly, at the time NeXT announced the cube (Aug 1988 according to Byte, Nov 88) 100ns was the fastest readily available memory - but I'm not sure. Maybe someone who knows better will post...? Thor UiB Norway me@fiol.uib.no <- NeXT mail, er du snill!
