The AUI port already defines you at 10 Mb/s. You need a different ethernet controller, as the speed is decided by the controller and not the PHY. On the Alpha it does, but I have never tried the VAX, I would think it should, it does in the Stromasys and Simh emulators, but I'm guessing. That is because Alphas actually might have a 100 Mbit/s ethernet controller. No VAX that I know of do. An emulated machine is a totally different topic. There you are still emulating a 10 Mb/s interface, even though it might map towards a 100 Mb/s physical backend. There are faster network interfaces for VAXen, just not Ethernet. It still wouldn't be an "apples to apples" comparison, but it'd be closer. -Dave -- Dave McGuire, AK4HZ New Kensington, PA
