Dual 500 cards are based on 7410 chips, not 7455. Our Cube designs use 745x chips; the 7410 is obsolete technology, although still in production; Motorola's fastest speed on the 7410 is the 500mhz L spec (105 degree C.) >> However duals require 7455 and the >> slowest 7455 is 867MHz, so that blew our plans. The 700s were 7450 >> chips. > > Hmm how does it comes that there are Dual 500?? Where's the difference?? > > Boris
