Hi, my MicroVAX II also makes this whiney sounds when working. But it's more like a fizzling, not very loud. I think it comes from the memory or the other chips inside there. It seems to be a "digital" sound :-) Regards Felix -- +++ GMX - Mail, Messaging & more http://www.gmx.net +++ NEU: Mit GMX ins Internet. Rund um die Uhr für 1 ct/ Min. surfen!
