In fact, that sounds like a marketing trick. I guess our marketroids missed the boat on the A3000. While the 68030 is of course clocked at 25MHz, it does derive its timing from a 50MHz clock module. On the other hand, maybe Motorola missed out on it. More and more new CPUs are running bus clocks at 1/2 their ALU clock speed. And they're using the ALU clock speed to stamp the part. If you're targeting people who buy systems according to clock speed, you win that way. -- Dave Haynie Commodore-Amiga (Amiga 3000) "The Crew That Never Rests" {uunet|pyramid|rutgers}!cbmvax!daveh PLINK: hazy BIX: hazy "This is my mistake.
