- There's another factor that our genious didn't take into account, that is,
- the speed of the memory. 70ns memory won't hack it on a machine that is
- running at 150-200MHz. In case you didn't notice, 200MHz is a 5ns cycle,
- a bit smaller than, oh, say *70*.
-
- I know one 3rd party vendor, whose prices are significantly lower than DEC's
- on most products, just quoted me $6495 for 64MB of memory for the Sandpiper.
- DEC isn't too much higher than that, especially when you consider the price
- disparity in the DECstation-line memory cards.
